NOVELTY - A graphene insulating heat conducting film, comprising a hollow metal foil, one side of the hollow metal foil formed on the surface insulating layer, and the other side surface is formed with the 1~3 layer graphene composite layer of the cascade, each graphene composite layer structure, from hollow metal foil outward in turn is adhesive layer, the graphene layer and PET film layer, and between the adhesive layer and the graphene layer or graphene layer and the PET film layer are uniformly formed with a layer of nano-silicon carbide. The utility model can both thermal conductivity and insulation, guarantee the safety of the electronic product and prolong the service life thereof.
