▎ 摘　　要

NOVELTY - Graphene-copper target material comprises a target assembly (1). The target assembly comprises an outer copper back plate (2) and a graphene copper target main body (3). The outer copper back plate is provided with a groove (4). The graphene copper target main body (3) outer wall is provided with a graphene plating layer (5). USE - Used as graphene-copper target material. ADVANTAGE - The graphene-copper target material has high strength and stable performance. The method: adjusts the structure and photoelectric performance of the copper target material, improves the performance of the copper target, ensures the reliability and anti-interference performance of the copper target, improves the high conductivity and high temperature stress resistance of the target; and has simple process and low production cost, and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene-copper target material. The method utilizes high-purity graphene, copper powder, argon gas, DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene-copper target material.
