▎ 摘　　要

NOVELTY - The film has a heating layer whose preparation material is provided with graphene, a polyvinylidene fluoride-hexafluoropropylene-polymer and a phase-change material. A glue protection layer is arranged on a front face and a rear face of the heating layer. An adhesive protection layer is made up of TPU hot melt adhesive or EVA hot melt adhesive. A packaging layer is adhered to the adhesive protection layer. The heating layer is arranged between two adhesive protection layers. Outer sides of two adhesive protection layers are provided with packaging layers. USE - Phase-change graphene heating film used for intelligent wearable clothes. ADVANTAGE - The film has excellent mechanical strength, heat conducting performance, heat conductivity, and phase change enthalpy value, and is manufactured by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a phase-change graphene heating film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a phase-change graphene heating film.
