▎ 摘　　要

NOVELTY - The foil has a graphene composite metal foil main body provided with a metal foil substrate and a planar graphene layer. The planar graphene layer is laid on the metal foil substrate by high-pressure electrostatic spraying in flat manner. The metal foil substrate is provided with a copper, aluminum or nickel foil substrate, where thickness of the planar graphene layer is about 10nm-200nm. USE - Graphene composite metal foil. ADVANTAGE - The foil simplifies preparation operation of the graphene composite metal foil main body, and adjusts thickness, width and length of a graphene covering layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene composite metal foil preparing method. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph view of a graphene composite metal foil.
