▎ 摘  要

NOVELTY - Preparing graphene copper composite material comprises continuously casting mixture of copper powder and graphene in vacuum condition, where the mass percentage of the graphene is less than or equal to 2%, the temperature of the continuous casting is 1050-1250℃, and the speed of the continuous casting is not more than 15 mm/minute. USE - Preparation method of graphene copper composite material used in fields of modern electronic information industry and power transmission industry. ADVANTAGE - The method enables to prepare graphene copper composite material, which improves the conductivity of the copper material with certain compression strength rate of copper. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene copper composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the preparation method of graphene copper composite material used in fields of modern electronic information industry and power transmission industry (Drawing includes non-English language text).
