Traditional paper dyes are easy to fade under photothermal conditions, in contrast. waterborne organic pigments have excellent tinctorial strength and high light and weather resistance, which can meet the requirements of highend paper yarn to coloring efficacy and light fastness of the colorants. However, the lack of chemical and hydrogen bonds between organic pigment particles and plant fibers, and the pigments are difficult to fix in the structure of the paper. In this study, cellulose nanofibers (CNF/TOCNF) were used as the primary skeleton network and carboxymethyl cellulose (CMC) macromolecules were used as the secondorder reinforcement network, together construct a multilevel gradient network to enclose and fix organic pigment particles. The dispersion and fixation of the pigment particles are realized by double coating. The results show that the coloring efficacy and colorfastness of the paper yarn base paper can be improved significantly by using the gradient network to fix the pigment particles, and has a positive effect on improving the strength and roughness of the paper. This study has an important role in solving the problem of coloring technology in the production of high-end paper yarn. [ABSTRACT FROM AUTHOR]

Solar-powered desalination is considered to be a technology can resolve the shortage of fresh water resources effectively. However, most of the photothermal conversion materials used in this technology adopt a combined structure, and the material is difficult to realize the floating, which need to use oil-based foam as a carrier of the foundation. Therefore, using MXene (Ti3C2Tx) for light absorption material, biodegradable nanocellulose (CNF) and sodium alginate (SA) as skeleton materials prepared a kind of environmental and can realize the floating MXene/CNF/SA bilayer photothermal conversion material (M-CSA). The structure and properties of M-CSA bilayer photothermal conversion materials were studied. The results showed that when 0.30 wt. %MXene is added, the solar absorptivity of M-CSA bilayer photothermal conversion material could reach 95.87%, and the evaporation rate could reach 0.93 kg·m-2·h-1 under one sun illumination [ABSTRACT FROM AUTHOR]

Plant fibers based foam material is very promising in replacing the foam plastic. It is of great significance to study the stability of the foam and the structure of the foam material for the development of plant fibers based foam material. In this study, plant fiber was used as the raw material and dodecanol was used as foam stabilizer to obtain plant fibers based foam material, and the effect of content of dodecanol on wet foam stability and foam structure was studied. The results show that the regulation of foam stability can be achieved by regulating the content of dodecanol, and then the regulation of structure of plant fibers based foam can be realized. The stability of wet foam was better and the structure of the foam material was superior when the content of dodecanol was 3. 5%. [ABSTRACT FROM AUTHOR]

Second fiber was epoxidated by using epichlorohydriri as etherifying agent. Effects of reaction time and reaction temperature on degree of substitution and epoxy value of the modified fiber were studied. Tt was indicated that they increases with pro longing of reaction time or increment of reaction temperature under 70。C, The characteristic absorption peaks of epoxidated fibers were observed from TR spectrum, which showed a lot of hydroxy Is on the fiber surface were replaced by the methyl epoxy group of epichlorohydrin. The calculations based on XRT) photo showed the crystalliriity was reduced to 21 A0% with the increased gap between molecular chains of modified fiber. TGA analysis indicated that thermal stability of fibers decreased slightly after modification. Tt was concluded in this paper that the rate constant of epoxidation of second fiber was ordered by 0J 1，0,25，0.35 under reaction temperature of 60,70 and 80, respectively. Activation energy of fiber epoxidation was 48.14 kJ/moL. [ABSTRACT FROM AUTHOR]

Using carbon nanofibers （CNFs） network structure to fix three-dimensional acicular zinc oxide （ZnO） whiskers, thereby preparing an intermediate layer of ZnO/CNFs, and through the tortuous pore channels of the intermediate layer, the shuttle path of lithium polysulfide is prolonged, so that it can Stably inhibits the "shuttle effect" of lithium-sulfur batteries through chemical adsorption and physical adsorption. Characterization results such as charge-discharge test and cycle test show that the initial discharge capacity of the battery reaches 1458 mAh·g-1 at a current density of 0.1 C, The coulombic efficiency remains at 99.4%;at a current density of 0.5 C, the initial discharge capacity can still reach 1113 mAh·g-1,and after 300 cycles of charge and discharge, the discharge capacity remains at 734 mAh·g-1.
