▎ 摘 要
NOVELTY - The utility model claims a graphene composite film has high earthquake buffer performance, comprising a graphene layer, foam layer, and copper foil layer. the top surface of the graphene layer is set on the first adhesive layer, the graphene layer on the bottom surface is provided with a second adhesive layer, the bottom surface of the foam layer by a first adhesive layer disposed on the top surface of the graphene layer. the top surface of the copper foil layer by a second adhesive layer set on the bottom surface of the graphene layer, the bottom surface of the copper foil layer is provided with a third adhesive layer composite film adhering of the utility model fixed on the external electronic device, wherein the foam layer is a double-layer composite foam, comprising an insulating foam layer and high elastic foam layer. This utility model through set, improves the shock resistance of the composite membrane of the utility model.
