▎ 摘　　要

NOVELTY - The composite carbon nano material has carbon nano material layer, a metal buffer layer and a matrix layer that are sequentially stacked. The metal buffer layer and the carbon nano material layer are connected in a solid solution structure and connected to base layer with an alloy structure. The carbon nano material layer is made of carbon nanotubes, graphene or fullerene. The thickness of carbon nano material layer is 10-100 mu m. The metal buffer layer is made of metallic iron, metallic cobalt, metallic nickel, or is made of alloy material with iron, cobalt and nickel as main structure. USE - Composite carbon nano material. ADVANTAGE - The composite carbon nanomaterial is configured to solve the problem that the carbon nano material is combined with the metal material under the condition that the bonding agent is not used. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite carbon nanomaterial. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structure of the composite carbon nano material. (Drawing includes non-English language text)
