▎ 摘　　要

NOVELTY - A graphene-metal composite material manufacturing method involves mixing graphene quantum dots and/or graphene microchip with nano metal element/nano metal compound under ultrasonic action and grinding to obtain composite slurry material or composite powder material. The composite slurry material or composite powder material is dried to obtain anhydrous composite powder material. The anhydrous composite powder material is quenched and refined by laser treatment to promote molecular rearrangement and graft fusion to obtain graphene-metal composite material. USE - Method for manufacturing graphene-metal composite material that is utilized in dental planting, super electric drill, other materials processing areas, battery, super capacitor energy storage materials, catalyst materials, thermal materials, medical field, coating materials, conductive ink, photoelectric field, sensor materials and biological related fields. ADVANTAGE - The method enables manufacturing the graphene-metal composite material with high hardness, high strength and low resistivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene layer-metal composite material.
