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.
