  • Environmentally-friendly flexible conductive polyurethane (PU) and preparation method thereof
    Patent number: 11987662
    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.
