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]

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.
