▎ 摘　　要

NOVELTY - Method for preparing graphene metal composite material comprises (a) growing graphene on surface of the metal material, (b) heating metal material growing with graphene to form a sintering or melting state, applying pressure to metal material grown with graphene, and (c) cooling metal material growth with graphene. USE - The method is useful for preparing graphene metal composite material, which is useful in field of alloy preparation for electrical, mechanical, and thermodynamic applications. ADVANTAGE - The method avoids growth and sintering need to replace the device, changing the growth position and so on the operation flow is long, high energy consumption and waste, does not reduce the performance of the composite material, really realizing one-step preparation, improving the growth efficiency, and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene metal composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the method for preparing graphene metal composite material (Drawing includes non-English language text).
