▎ 摘　　要

NOVELTY - The method involves performing surface modification of graphene thermal conductive substrate. The surface-modified heat graphene conducting base material is coated and wrapped to form a covered edge layer. a covering film wrapping layer (120) is tightly attached to the surface and the edge of the heat graphene base material. The material for covering film wrapping comprises one or mixture of more of parylene, styrene and acrylic ester compound. The parylene includes dichloro-para-xylene dimer, para-xylene dimer, tetrachloro-para-xylene dimer and octafluoro a mixture of one or more of the paraxylene dimers. The acrylate compounds include methyl methacrylate, methyl ethacrylate, methyl vinyl acrylate, propylene Methyl alkenoate, ethyl methacrylate, ethyl ethacrylate, vinyl ethyl acrylate, ethyl acrylate, methacrylic acid and a mixture of one or more of butyl ester, butyl ethyl acrylate, butyl vinyl acrylate, and butyl acrylate. USE - Film-coated edge wrapping method of graphene thermally conductive base material used in graphene heat-conducting film of radiating film in electronic product (all claimed). ADVANTAGE - The coating wrapping graphene of the heat-conducting base material has good adhesion, voltage resistance and high temperature resistance, and suitable volume and thickness, and is suitable for electronic product application scene with strict limit to the size, simple processing technique, high efficiency and low cost. The graphene heat conducting film formed by covering film has good voltage resistance, insulating property, good thermal conductivity, and good bending property and flexibility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a graphene heat-conducting film; and a radiating film. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic diagram of the graphene the heat conducting film. 100Graphene heat conducting film 110Graphene heat-conducting base material 120Covering film wrapping layer
