▎ 摘　　要

NOVELTY - The preparation method involves depositing graphene by chemical meteorological deposition using raw material metal as base material to obtain a metal material having a graphene layer deposited on the surface. The metal raw material deposited with the graphene layer is heated under an oxidizing atmosphere to make the graphene layer uniform to obtain a graphene-metal composite raw material. The graphene-metal composite raw material is stacked in a predetermined order and sintered to produce a graphene-metal composite material. USE - Preparation method for preparing graphene-metal composite material. ADVANTAGE - Obtains lightweight and strong graphene-metal composite material with improved conductivity. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of an oxidation smoothing process. (Drawing includes non-English language text).
