Abstract: An environmentally-friendly flexible conductive polyurethane (PU) and a preparation method thereof are disclosed. The environmentally-friendly flexible conductive PU is prepared by subjecting a mixture of a component A and a component B in a specified mass ratio to in-situ solvent-free polymerization, where the component A is prepared from a polyol, a T-type chain extender, a diselenide diol, high-conductivity carbon black, a dispersing agent, a catalyst, and a leveling agent, and the component B is prepared from a polyisocyanate, a polyol, a multi-walled carbon nanotube (MWCNT), and a dispersing agent. The PU has a reliable electrically-conductive function, and shows a self-healing function under room temperature or light conditions when damaged, wherein a microphase separation value HBI (0.5 to 3.0) of soft and hard segment molecules can be adjusted to achieve different hand touches and different mechanical properties, and an organic pollutant emission (volatile organic compound (VOC)) is less than 50 mg/kg.

Abstract: A method for preparing a carbon nano tube/polyacrylic acid hydrogel, a product and an application thereof are provided. The method includes: oxidizing a carbon nanotube into a carboxylated carbon nanotube, thereafter performing in-situ polymerization with acrylic acid, sodium hydroxide, ammonium persulfate, triethanolamine and N, N-methylenebisacrylamide to obtain a carbon nanotube/polyacrylic acid hydrogel. The hydrogel has a uniform porous structure, facilitating a rapid transmission and supply of water. The carbon nanotubes in the hydrogel are of an array structure, achieving a full absorption of solar energy to realize a high-efficiency photothermal conversion. The gel is attached to a sponge base to obtain a solar-powered carbon nano tube/polyacrylic acid hydrogel steam generator for the photothermal conversion. The steam generator is used for solar seawater desalination, but can improve evaporation rate and evaporation efficiency. In addition, the steam generator has many advantages, such as energy conservation, environmental protection, simplicity and practicability.
