In this work, fibrous polypyrrole/epoxy composites are successfully prepared using epoxy resin as the matrix and fibrous polypyrrole prepared by oxidation template method as the doping material. The crystal structure and morphology of the polypyrrole filler are analyzed by means of X-ray diffractometer, scanning electron microscope and Fourier infrared spectrometer. The effects of different contents of fibrous polypyrrole on the mechanical properties and wave absorption properties of the composites are investigated. The results show that a small amount of fibrous PPy can improve the tensile strength of the composites, and the tensile strength of 3 wt% PPy/epoxy resin composites reaches 80.1 MPa. The resistivity of PPy/composites decreases significantly with the increase of PPy filler content. The 3 wt% PPy/epoxy composite exhibits excellent wave absorption performance with a minimum reflection loss RL of-33.50 dB at 16.1 GHz. This work provides guidance for the preparation of epoxy resin-based nanocomposites to deal with electromagnetic wave pollution. [ABSTRACT FROM AUTHOR]

In view of the uneven distribution of airflow inside the multi-air-duct sprayer, the air flow caused by the air outlet is disturbed and the droplet can not be evenly deposited on the fruit tree canopy. In this research, the length parameter of the inner baffle plate of the multi-duct sprayer was optimized. The Computational Fluid Dynamics (CFD) was used to simulate and analyze the internal airflow of the air supply system of the multi-duct sprayer based on Star-CCM+ software. The standard deviations of the wind speed of the wind outlet 1~6 at different guide plates were 0.7468, 0.6776, 1.4441, 5.1305, 4.5768 and 0.8209, respectively. Among them, the standard deviations of wind speed value at Point 1, Point 2 and Point 6 were less than 1, indicating that the change of deflector length has little impact on the speed change. The standard deviations of wind speed value at Point 3, Point 4 and Point 5 were large, indicating that with the change of deflector length, the wind speed at Air outlet 3, Air outlet 4, Air outlet 5 were greatly affected. On this basis, through the response surface analysis of Air outlet 3, Air outlet 4 and Air outlet 5, it was determined that, the length of Deflector 1 as 200 mm, the length of Deflector 2 as 60 mm and the length of Deflector 3 as 50 mm, was the optimal parameter combination. Under the optimal combination parameters, the wind speed values of symmetrical Air outlet 3 and Air outlet 6 were 39.135 and 41.320 m/s, respectively, with a relative deviations of 5.58%. The wind speed values of air outlet 4 and air outlet 5 were 33.022 and 34.328 m/s, respectively, with a relative deviation of 3.95%, which meeting the design requirements of sprayer. The indoor wind speed test results showed that the average wind speed of the upper layer was 15.75 m/s, the average wind speed of the middle layer was 20.83 m/s, and the average wind speed of the lower layer was 28.27 m/s, which met the end speed principle. The wind field was distributed according to the shape of the fruit tree canopy. The wind field of the left and right sides of the sprayer was symmetrical distributed and the air distribution was uniform. The work can provide a reference for the design of multi-duct sprayer [ABSTRACT FROM AUTHOR]

Hyper-cross-linked polymers（HCPs）have been one of the hotspots of the porous organic polymers because of their high Brunauer-Emmett-Teller （BET） surface area （SBET） and unique porosity. Moreover， their simple synthetic procedure of one-pot Friedel-Crafts reaction and various aromatic monomers make HCPs one of the hotspots of porpous organic polymers. Porphyrins are a kind of macromolecular heterocyclic compounds formed by the interlinking of four α-carbon atoms of pyrrole subunits via submethyl bridges. It can form stable complexes with a variety of metals，and has good applications in the adsorption and detection of heavy metals，adsorption and separation of gases，etc. However，the reported porphyrin-based HCPs in the literature are almost fabricated according to the Friedel-Crafts alkylation，while the Friedel-Crafts acylation reaction is rarely reported. The ketone-functionalized porphyrin-based HCPs based on the Friedel-Crafts acylation possess plentiful acyl groups，which offers a potential prospect for their further functionalization. However，these ketone-functionalized HCPs own very poor porosity，and their construction of unique porosity for this kind of HCPs is of great significance. Herein，the Friedel-Crafts acylation was performed for tetraphenylporphyrin and pyromellitic dianhydride，and the synthesized ketone-functionalized HCPs were further carried out for the Schiff-base reaction using melamine as the reactant. The resulting melamine- modified porphyrin-based HCPs exhibit medium SBET（118 m²/g），excellent hierarchical porosity，and high N content（46. 28%），indicative of its outstanding CO2 capture and Hg2+ removal，the CO2 uptake is 93 mg/g at 273 K and 101 kPa，and the Hg2+ adsorption reaches equilibrium within 30 min with the maximum capacity of 494. 1 mg/g.
