Conductive polymer composite with segregated structure has been well demonstrated to achieve high electromagnetic interference shielding effectiveness (EMI SE) due to the selectively distributed electrical nanofillers to establish desirable conductive networks. Nevertheless, the formation of segregated structure in low-melt-viscosity semi-crystalline polymer is still challenged and the segregated composite always suffers poor mechanical performance. Herein, elevated pressure and temperature were utilized to make a typical semi-crystalline polymer, polypropylene (PP), hold solid phase to restrict the diffusion of carbon nanotube (CNT) into its interior. Segregated CNT networks were facilely constructed in the resultant CNT/PP composite and imparted it with a superior EMI SE of 48.3 dB at 2.2 mm thickness and 5.0 wt% CNT loading, the highest EMI shielding level among the reported CNT/polymer composites at equivalent material thickness and CNT loading. Moreover, the elevated pressure and temperature effect dramatically increase the compressive, tensile, and flexural strength (modulus) of the CNT/PP composite by 133% (65%), 74% (130%) and 53% (50%), respectively, in comparison to those for conventional segregated CNT/PP composite, really overcoming the major mechanical shortcoming in the development of segregated composites for EMI shielding. Our work provides a facile strategy to fabricate the efficient EMI shielding and robust material with the construction of typical segregated structure in low-melt-viscosity semi-crystalline polymers.

The rapid development of highly integrated and multifunctional electronic devices urgently requires polymer composites with anisotropic thermal and electrical conductivities and electromagnetic interference (EMI) shielding. Herein, the precise control of high alignment and alternating distribution of graphite (Gt)-carbon nanotubes (CNTs) and hexagonal boron nitride (h-BN) via co-extrusion to fabricate alternating multilayered SR composites were reported. Such ordered hierarchical structures not only constructed efficient thermally and electrically conductive networks within the layer but also effectively segregated the electrical and thermal conduction path in the through-plane direction. Simultaneously, owing to the destructive interference of EM waves between the two Gt-CNTs layers, resulting in significant improvements in total shielding effectiveness along with obvious shielding peak shift with decreasing the thickness of the h-BN layer. The 4-layer SR composites exhibited anisotropic thermal and electrical conductivities and frequency-selective EMI Shielding. Specifically, the 4-layer SR composites exhibited in-plane thermal conductivity of 8.71 W/mK, breakdown voltage of 8.0 kV/mm and EMI shielding effectiveness of 31–43.2 dB, when the thickness ratio of the Gt-CNTs layer and the h-BN layer was 4:1. Furthermore, the ordered hierarchical structures of the SR composites could be directionally transformed through stacking-cutting to meet different heat dissipation and electrical conduction application scenarios. This research provides new insights into the simple preparation, rational design and multifunctional integration of polymer composites for advanced electronic devices.

Abstract: Thermally conductive polyethylene (PE)/boron nitride (BN) composites were prepared by multistage stretching extrusion without any surface treatment of BN. Effects of the intensity of the shear field on the distribution of the BN particles were characterized by scanning electron microscope (SEM). The thermally conductive behaviors, rheological and mechanical properties of the PE/BN composites were also investigated. The results showed that the strong shear field in 8LMEs was helpful to improve the dispersion of the BN particles in PE matrix so that much more thermally conductive paths can be built in form of the filler–crystal–filler in PE matrix at large concentration of the BN particles. To well understand the thermal conduction mechanism of the PE/BN composites, the heat conductive model was proposed. According to this model, a large BN aggregates existed in PE matrix. However, the BN aggregates were damaged due to the strong shear field so that much more thermally conductive paths (connection via filler–crystal–filler) can be built in the PE/BN composites. Therefore, the thermal conductivity of the PE/BN composites was improved after multistage stretching extrusion processing. Meanwhile, it was found that the strong shear field was helpful to enhance the storage modulus, complex viscosity, tensile and impact strength of the PE/BN composites. Therefore, the processing method of multistage stretching extrusion can not only enhance the thermal conductivity of the PE/BN composites but also improve their mechanical properties.

Boron nitride nanosheets (BNNS) have promising applications in thermal management materials, due to their high thermal conductivity and low dielectric loss. However, it is still challenging to fabricate BNNS with large lateral size and structural integrity via solvent-free methods. Here, we report a novel processing method for in-situ exfoliation of hexagonal boron nitride (h-BN) to fabricate BNNS with an average lateral size of 1.45 μm, average thickness of 4.88 nm and few lattice defects during the forced flow of polylactide (PLA) in a highly elastic state. We further fabricate flexible and bio-degradable PLA/BNNS electrospun fibrous film for electronic devices to replace petroleum-based composites. The PLA/BNNS fibrous film exhibits an in-plane thermal conductivity of 4.9 W/(m·K) at the BNNS loading of 20 wt%. Moreover, the fibrous film also has a low dielectric loss (0.007 at 1 kHz) and good electrical insulation. The in-situ exfoliation strategy is simple, economical and environmentally friendly, providing an effective route to design thermal management materials with high thermal conductivity and low dielectric loss in the future of electronic devices.

The performance of the electrothermal film is generally determined by conductive filler network. However, it is still challenging to construct a dense network of conductive fillers in the electrothermal film. In this work, we develop a simple and efficient method to construct a dense and continuous network via in-situ growth of CuS nanosheets on the surface of polyimide (PI) film with stable interfacial bonding. The obtained PI@CuS electrothermal film is further packaged by commercially available PTFE and PI tapes to achieve desirable surface hydrophobic self-cleaning function and stability for the use in different environments. By tuning the network density of CuS nanosheets, it imparts excellent electrothermal conversion efficiency and cycling stability to the PI@CuS film, whose surface temperature could rapidly ramp up over 200 °C at 8 V. The film also exhibits excellent photothermal performance, reaching close to 100 °C at 100 mW/cm2. The anti-icing/de-icing experiment shows that the icing time is prolonged significantly at low temperature and the melting time is reduced dramatically. Furthermore, the PI@CuS film also exhibits outstanding electromagnetic interference (EMI) shielding effectiveness of 57.1 dB with a thickness of only 80 μm, and excellent tensile strength of over 90 MPa. The in-situ growth strategy provides a novel route for the fabrication of the electrothermal film with excellent overall performance.

Abstract: Mesoporous CaCO3 microparticle-doped alginate composite gels were prepared and studied as efficient carriers for enzyme immobilization. β-Glucuronidase (GUS) was immobilized by first pre-adsorption on CaCO3 microparticles and then encapsulation in alginate beads. In this hybrid composite, alginate matrix effectively prevented the desorption of enzyme and inhibited the recrystallization of CaCO3, while the impregnated CaCO3 particles remarkably reduced the swelling of alginate hydrogel from 130% to 20%. As a result, GUS loading efficiency, recycling and storage stability were all significantly improved. Immobilized GUS retained 80% of its initial activity after seven recycles and 67% after storage for 27 days. [Copyright &y& Elsevier]

It is still a challenge to fabricate polymer composites with superior gas barrier properties, which is highly demanded in aircraft tire lining with a high gas pressure (1.5 MPa). Herein, a versatile method to fabricate polymer composites with a dense dual network structure via ball-milling was developed. In such a structure, the graphite was in-situ exfoliated to edge-selectively carboxylated graphene (ECG) nanosheets, which were first embedded into ternary copolymerized polyamide (PA) particles to construct an inner well-dispersed network. Subsequently, ECG nanosheets were selectively distributed at the interfaces between resultant particles of PA composites to form an external interconnected network. It was found that the dense dual network of ECG prolongs the pathways for diffusing gas molecules, compared with the pristine PA, up to a 20-fold decrease in nitrogen permeability of ultimate PA composites (from 0.233 × 10−17 to 0.0113 × 10−17 m2 S−1 Pa−1) were obtained with only 2 wt% ECG nanosheets. The excellent gas barrier properties were ascribed to the synergistic effect of the dual network. This work provides an efficient, scalable, low-cost and eco-friendly route to fabricate high-barrier polymer composites. [Display omitted] [ABSTRACT FROM AUTHOR]

In this paper, two poly(styrene- b -ethylene-ran-butylene- b -styrene) (SEBS) with different styrene segment content were adopted to explore the relationship between varying π-π stacking interaction and the mechanical performance of polymer composites. The results showed that the high styrene content on SEBS (SEBS-30, 30 wt% styrene segment) endows SEBS a stronger π-π stacking interaction with GO and a better dispersion of GO in the matrix than that in SEBS with low styrene content (SEBS-12, 12 wt% styrene segment), resulting in a high efficiency on enhancing the performance of SEBS. By adding 0.5 wt% GO, the tensile strength and modulus of SEBS-30 was increased by 44% and 64%, respectively, while that of SEBS-12 was increased by 24% and 39%. Furthermore, the GO also exhibited the ability to toughen SEBS via forming microcrack and GO-induced fibrillation of SEBS during the fracture process. The elongation at break and fracture toughness of SEBS-30 was increased by 10% and 64%, respectively. This study gives us a deep insight into the influence of varying π-π stacking interaction between graphene oxide (GO) and polymer on achieving high-performance polymer nanocomposites.

The interfacial interaction in polyamide/tin-fluoro-phosphate glass (TFP-glass) composites exhibits a positive correlation with temperature, whose mechanism is still unknown. The thermal-induced dissociation behavior at 232 °C of TFP-glass, which has been observed and investigated in our previous works, provides a plausible mechanism for the temperature-dependency of the interfacial interaction. In this work, the influence of the dissociation degree, which is controlled by processing temperature, on the interfacial interaction between TFP-glass and copolymerized 6/66 copolymer (cPA) is investigated. Three processing temperatures, 215, 230, and 245 °C (below, around and above the dissociation temperature of TFP-glass, T d  = 232 °C), are chosen to prepare cPA/TFP-glass composites. With increasing the degree of dissociation, improved dispersion of TFP-glass particles in polymer matrix and enhanced interconnection between the two components are observed, indicating that the interfacial interaction in cPA/TFP-glass composites is gradually enhanced. The dielectric relaxation spectra, which can probe the local motions of macromolecular fragments at different length scales, are used to investigate the influence of the dissociation degree on the length scale of the interfacial interaction in cPA/TFP-glass composites. The improved thermal stability of cPA/TFP-glass composites filled with the same content of TFP-glass also confirms the enhancement of the interfacial interaction. Therefore, conclusions can be drawn that the dissociation behavior of TFP-glass is contributed to the temperature-dependency of the interfacial interaction in polyamide/TFP-glass composites. The work reported in this paper should provide theoretical guidance for taking advantage of this positive correlation with temperature of the interfacial interaction and help us to deeply understand the mechanism for the interfacial interaction in TFP-glass filled composites.

In this paper, graphene oxide (GO) was functionalized with tannic acid (TA), an easy-available and low-cost plant, on the GO surface through simple ultrasound-/shearing-assisted solution blending. The TA endows GO a stronger interfacial interaction with poly (styrene-b-ethylene-ran-butylene-b-styrene) (SEBS) and greatly improves the dispersion of GO in the SEBS, resulting in a much high efficiency of GO on improving the performance of the matrix. By adding 10 wt % of TA-GO (weight ratio of TA and GO = 2:1), the dielectric constant of SEBS matrix at 100 Hz reached up to 58.7, about 27-fold and 7-fold increment compared with that of neat SEBS and SEBS/GO nanocomposites, respectively. Moreover, compared with neat SEBS, the tensile strength, modulus and fracture toughness of SEBS/TA-GO nanocomposites with the addition of 0.5 wt% of TA-GO were enhanced by 122%, 91% and 107%, respectively. GO-induced firbous SEBS and microcrack formed around GO were found and proposed as the toughening and reinforcing mechanism of TA-GO in SEBS. This study not only provides a strategy to prepare high-performance SEBS nanocomposites, but also puts forward a facile, easy, low-cost and effective strategy to enhance the graphene-polymer interfacial interaction and improve the dispersion of graphene in the polymers.

The heat dissipation property of the thermally conductive and electrically insulating composites can be enhanced by constructing high efficiency thermally conductive pathways, while the mechanical properties of the final composites are always neglected. In this work, graphite (Gt), a typical carbon based filler with excellent thermal conductivity, was highly oriented and uniformly dispersed in polymer matrix to keep the electrical resistivity of the composite at a high level, even when the content of Gt was 33 wt%. Then, in order to further improve thermal conductivity, the consecutive and high efficiency thermally conductive yet electrically insulating pathways were constructed by adding silicon carbide (SiC) particles into the composites as junctions to release the thermally conductive potential of Gt via forming phonon transport channels. As a result, thermal conductivity reached 1.68 W/(m × K) when the content of SiC was 20 wt%. Meanwhile, the in-plane thermal conductivity (along the melt flow direction) was as high as 3.8 W/(m × K), which was over 5-fold larger than the through-plane thermal conductivity (along the thickness direction). Subsequently, Agari model and thermally conductive simulation based on the finite element analysis were also applied to give a deep insight into the effect of this special filler architecture on the heat dissipation performance of the composites. Furthermore, mechanical properties of such composites were also largely enhanced. Therefore, building up high efficiency thermally conductive and electrically insulating pathways through highly oriented and uniformly dispersed 1-D or 2-D anisotropic carbon based fillers close-packed with another kind of uniformly dispersed thermally conductive and electrically insulating fillers is a simple and effective method to endow the composites with excellent thermal conductivity, high electrical resistivity and great mechanical properties simultaneously.

Neutron radiation is often encountered in a wide range of industries, such as aerospace, healthcare and nuclear power plants. It has been an arduous challenge to shield this neutron radiation to improve equipment safety and protect human health. In order to make an effective neutron shielding material, alternating multi-layered composites (high density polyethylene)/(high density polyethylene/boron nitride), (HDPE/(HDPE/BN)) and (HDPE/BN)/(HDPE/Barium sulfate (BaSO 4 )) were fabricated using a multi-layered co-extrusion system. The HDPE/BN layers in the alternating multilayered HDPE/(HDPE/BN) and (HDPE/BN)/(HDPE/BaSO 4 ) composites had a continuous and layered distribution in their structure, with the BN particles oriented in the extrusion direction. The probability of collision between incident photons and flake-shaped particles is enhanced through alignment of the oriented BN particles. In this way, neutron transmittance noticeably decreased with an increasing number of layers. Compared to traditional polymer-blended materials, the alternating multilayered composites showed excellent shielding efficiency. In addition, the results of the dynamic rheological analysis showed that alternating multi-layered composites with more layers can weaken the cross-linking effects induced by secondary radiation. Furthermore, according to the Nano-TA analysis, BaSO 4 was an effective shield of secondary radiation, so the average melting point, in nanoscale, can be represented as follows: (Nano- T m ¯ ) ((HDPE/BN)/(HDPE/BaSO 4 )) > Nano- T m ¯ (HDPE/(HDPE/BN)).

To simultaneously resolve an undesirable electromagnetic wave and heat emissions that were caused by an electronic device, an electromagnetic interference (EMI) shielding material with excellent electrical insulation and high thermal conductivity was urgently required. However, keeping the EMI shielding material on electrical insulation still remained a challenge due to the superior electrical conductive network in it. We fabricated an ordered multilayer film through casting layer (graphene oxide/poly(-hydroxybenzate- co -DOPO-benzenediol dihydrodiphenyl ether terephthalate)) by layer (boron nitride/(maleated styrene-ethylene/butylene-styrene)), and the special architecture of the film not only simultaneously built the superior electrical and thermal conductive network in-plane direction, but also effectively blocked the electrical conductive path through-plane direction. Moreover, the ordered multilayer film (11 layers) exhibited a good EMI shielding effectiveness (37.92 dB), excellent electrical insulation (breakdown strength was 1.52 MV/m) and high thermal conductivity (12.62 W/mK) in-plane direction, indicating that the ordered multilayer film was a novel promising candidate for an ideal EMI shielding material with excellent electrical insulation and high thermal conductivity in today's electronic devices.

Friction and wear properties of polyamide (PA) materials can be improved by graphite (Gr) due to its superlubricity. For further enhancing the ultimate properties of composites, the interfacial adhesion between Gr and PA has already attracted growing attention, while the contribution of Gr arrangement is often ignored. In this work, the interfacial adhesion was improved by π-π interactions between Gr and 1,3-Bis(4,5-dihydro-2-oxazolyl)benzene (BOB) functionalized PA6 via reactive extrusion. Moreover, the highly oriented structure of Gr was achieved by the strong extensional and shearing field. Experimental results indicated that BOB functionalized PA6 with 20 wt% highly oriented Gr (PA6-BOB/HOGr20) displayed excellent balanced performance. Compared with pure PA6, the coefficient of friction (COF) and specific wear rate of the PA6-BOB/HOGr20 composite were reduced by nearly 42% and 46%, respectively. Furthermore, its in-plane thermal conductivity (TC) reached as high as 2.14 W/(m K). Due to the low COF and high TC, the tribo-surface temperature was consistently lower than its glass transition temperature (T g) under harsh pressure-velocity (PV) conditions of this experiment. In addition, the PA6-BOB/HOGr20 composite still has high ductility, and the elongation at break reaches 150%. This work provides a facile and environmentally friendly method for designing high-performance wear-resistant composites, which can be used as linear guide rail, liner, and linear bearing in industrial applications.

The application of dielectric lossy absorbent, multi-walled carbon nanotubes (MWCNTs) filled polymer as a microwave absorbing material (MAM) is limited because of the high loading level. Optimizing the distribution of MWCNTs in a polymeric matrix was a key factor in obtaining better microwave absorption while keeping the MWCNT content low. According to the theory of transmission lines, we designed an alternating multilayer structure with MWCNTs distributed in the continuous and parallel layered spaces of a poly (vinyl chloride) matrix to improve its microwave absorbing properties. The effect of the layer number on the microwave absorbing capacity was studied by theoretical calculations and experimental measurements. The results showed that the −10 dB absorbing bandwidth and the absolute value of the minimum reflection loss of alternating layered samples were higher than those of a conventionally blended sample with the same MWCNT content and increased with the increasing layer number. This improvement of the microwave absorbing capacity was mainly attributed to the multi-reflection of microwaves between the layered interfaces. Interestingly, the matching frequency of the alternating layered MAMs could be adjusted by changing the layer number. The measured microwave absorbing properties were well predicted by the theoretical model. In addition, the mechanical properties improved with an increasing number of layers. [ABSTRACT FROM AUTHOR]

The alternating multilayered damping composites, chlorinated butyl rubber (CIIR) as damping layer and polymethyl methacrylate (PMMA) as constraining layer, were first prepared through novel multilayered co-extrusion. The damping properties of the CIIR/PMMA multilayered damping composites were investigated by dynamic mechanical analysis (DMA). The results showed that the damping peak moved to high temperature and the efficient damping temperature range was broaden with the layer number increasing. The shift of the loss peak was ascribed to the move of Rouse mode of CIIR, which was attributed to the motion of longer chain segment, but the local segmental motion was not changed. Finite element analysis (FEA) was used to simulate the distribution of shear strain in the multilayered damping composites. The FEA results exhibited that, in the temperature range between Tg-CIIR and Tg-PMMA, the shear strain occurred in the CIIR layer under vibration field, since the storage modulus ( E ′) of PMMA was much higher than that of CIIR. Furthermore, the average shear strain was increased with the layer number increasing. [ABSTRACT FROM AUTHOR]

Fabrication of high-performance and multiple-function conductive polymer composites with uniform distribution and high content of carbon-based nanofillers has been a formidable challenge. In this study, a new strategy was introduced to fabricate polyoxymethylene (POM)/multi-walled carbon nanotube (MWCNT) and POM/graphene nanoplate (GNP) composites (PMCNT and PMGNP, respectively), with uniform distributions and high contents of MWCNT and GNP, by assisting of miscible poly(l -lactide) (PLLA). As expected, the composites exhibit robust electromagnetic interference (EMI) shielding, Joule heating, thermal conductivity, and anti-dripping performance. Specifically, the EMI shielding effectiveness of PMCNT40 (with 40 wt% MWCNT) and PMGNP48 (with 48 wt% GNP) reached 45.7 and 44.7 dB with 0.15 mm in thickness. The high electrical and through plane thermal conductivities were 3484 S/m and 1.95 Wm−1K−1, respectively, for PMCNT40, and the corresponding values for PMGNP48 were 2695 S/m and 4.24 Wm−1K−1, respectively. Furthermore, the fabricated composites achieved excellent Joule heating performance, resulting in increases in surface temperature increase to 101.4 °C and 107.6 °C rapidly at the driving voltages of 3.0 V (in case of PMCNT40) and 6.0 V (in case of PMGNP48), respectively. In addition, the composites exhibited excellent solvent resistance and anti-dripping performance, indicating high potential applicability in extreme environments.

Aramid fiber has been commonly used in EPDM-based insulators to enhance ablative resistance as the char layer skeleton, due to its good flexibility and low thermal conductivity. However, its thermal stability restricts the improvement of ablative performance to meet the growing requirements of Solid Rocket Motors. In this work, hybrid fiber network was constructed in char layer via the combination of aramid fiber (AF) and carbon fiber (CF), due to high thermal stability of CF. The results showed that linear ablation rate displayed a valley-shaped change as the CF ratio increases, and best ablative performance was obtained at the 1:1 ratio with the linear ablation rate reduced to 0.0604 mm/s, which was 31% lower than that of the insulator filled with only AF. Furthermore, the ablation mechanism was studied based on the evolution of char layer structure and the formation of char layer with CF shielded at surface and AF consolidated inside could account for the synergetic effect on ablation resistance. A char layer with carbon fiber (CF) surface shielder and aramid fiber (AF) consolidator was constructed by hybrid fiber network during the oxyacetylene ablation test and their synergy can be revealed in a proper hybrid ratio, which contributed to excellent ablative resistance with reduced ablation rate.

Highly thermal conductive polymer composites synchronously with excellent dielectric and mechanical properties are highly desired in electronic devices. In this work, largely enhanced thermal conductivity (TC), dielectric constant and mechanical property were synchronously realized in polycarbonate (PC) matrix via incorporating boron nitride (BN) together with few graphene nanoplatelets (GnPs) and carbon nanotubes (CNTs). Significantly reduced interfacial thermal resistance between BN and matrix in PC/BN@GnP@CNT composites was the main reason contributed to the largely enhanced TC. By synchronously adding 20 wt% BN (BN-20), 1 wt% GnPs and 1 wt% CNTs, the TC of PC/BN-20@GnP@CNT composites reached up to 1.42 W/mK, enhanced by 647% and 103% compared with that of neat PC and PC/BN-20 composites, respectively. The dielectric constant of PC/BN-20@GnP@CNT reached up to 177 at 100 Hz (enhanced by ~50-fold compared with PC/BN-20) while the dielectric loss was kept at a low level. Compared with PC/BN-20, the yield strength, elongation at break, fracture toughness and notched impact strength of PC/BN-20@GnP@CNT were enhanced by 42%, 103%, 146% and 8%, respectively. Meanwhile, PC/BN/GnP@CNT composites showed significantly reduced ignitability and remarkable anti-dripping performance. This work promotes an effective, feasible strategy for fabricating dielectric thermal conductive polymer composites with excellent mechanical and anti-dripping performance. [ABSTRACT FROM AUTHOR]
