摘要： 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.

摘要： Clothing weatherproofed by being coated with plastics material of low permeability to water vapor is uncomfortable to wear.The present invention provides a breathable polyurethane film for coating on fabrics to make them waterproof. The film comprises a hard segment formed by reaction of a low molecular weight difunctional compound with excess diisocyanate to form a prepolymer and a soft segment provided by polyethylene glycol with which the prepolymer is reacted in a stoichiometric amount. If desired the film can be formed by reacting the polyethylene glycol with excess diisocyanate to form a prepolymer which is then reacted with a stoichiometric amount of a low molecular weight difunctional compound. The mechanical properties of the film can be improved by cross linking with a cross linking agent such as a triisocyanate.
