▎ 摘　　要

NOVELTY - Preparation of metal-graphene composite material comprises using metal particles as an inner core and a graphene layer as a shell, doping the composite particles in molten metal, where in the molten metal the metal particles are in molten state, and the graphene layer is solid, and forming the metal doped with composite particles. USE - Preparation method of metal-graphene composite material. ADVANTAGE - The material can reduces the density difference between graphene and metal, effect of inhomogeneous distribution of alkenes in metals. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a metal-graphene composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flow chart of a method of a preparation method of metal-graphene composite material. (Drawing includes non-English language text).
