▎ 摘　　要

NOVELTY - A graphene polyurethane film comprises 60-88.45 pts. wt. polyurethane resin, 0.5-10 pts. wt. graphene or graphene composite, 1-15 pts. wt. carbon-based conductive filler, 2-10 pts. wt. dispersing agent, 0.5-5 pts. wt. auxiliary agent and solvent. USE - Graphene polyurethane film for producing heating material, such as flexible heating material, infrared flexible heating material or far infrared flexible heating material, and/or heating device such as wearable heating device, wearable flexible heat-generating device, wearable flexible infrared heat-generating device or wearable far-infrared flexible heat-generating device and/or heat-generating device is a flexible heat-generating device, an infrared flexible heat-generating device or a far-infrared flexible heat-generating device (all claimed). ADVANTAGE - The film exhibits excellent electrical conductivity of heating material, heat radiation performance, and radiation wavelength generated by the graphene close to the radiation wavelength of the human body, so the heat energy generated can be better absorbed by the body, with better far infrared heating effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene polyurethane film.
