NOVELTY - The utility model claims a high performance graphene, aiming at solving the whole material of the graphene wire covered by the film has better conductivity, but in the whole material of the graphene wire covered by the film, the content of the film is graphene, leading to conductive performance, mechanical strength of limited improvement, comprising a metal foil substrate layer; at least one layer of the graphene film layer covered on the metal foil substrate layer; a metal wire arranged on the edge of one side of the metal foil substrate layer; The metal foil substrate layer is tightly wound with a metal wire as a shaft core to form a graphene lead wire of a basic unit of graphene foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-graphene foil substrate layer-metal foil substrate layer-graphene foil substrate layer-metal foil substrate layer-metal foil substrate layer-graphene foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate layer-metal foil substrate The utility model is especially suitable for the actual application of the high performance of the graphene, and it has high social use value and application prospect.
