▎ 摘　　要

NOVELTY - Insulating graphene heating film comprises substrate, conductive layer, heating layer, first protective layer and second protective layer, where the heating layer comprises a thermally conductive graphene slurry and a phase change material, and in the heating film, the phase change materials are added to the thermally conductive graphene slurry to make a mixed slurry, so that the heating temperature of the heating film is 30-90 degrees C. USE - The film is useful in smart wearable apparel. ADVANTAGE - The film has excellent thermal properties, extends heating time of heating film, accelerates circulation of blood by a physiotherapy effect generated by far infrared light wave emitted by graphene, removes harmful substances in human body, and promotes metabolism of human body.
