▎ 摘　　要

NOVELTY - The composite material has a material structure formed by repeatedly arranging a graphene-metal structure according to a tightly stacking technique. Metal in the graphene-metal structure is formed with a metal foil (3), where the metal foil is preferably made of copper or nickel or copper nickel alloy foil. USE - Layer-by-layer structure graphene-metal composite material for use in various applications such as aerospace, automobile and military fields. ADVANTAGE - The composite material is dispersed uniformly, avoids the unstable performance of the plate after hot rolling, improves the binding graphene of the metal substrate, combines the metal graphene body more tightly and more uniformly, adjusts the thickness of graphene chemical vapor deposition by changing the deposition time to length, realizes graphene chemical vapor deposition on two sides of the copper, nickel, copper nickel alloy metal foil, integrates barrier phase growth of depositing graphene layer with simple process, and has better designability and better heat-conducting performance for providing mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing layer-by-layer structure graphene-metal composite material. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded view of the layer-by-layer structure graphene-metal composite material. 3Metal foil 4Graphene layer
