NOVELTY - Preparation of composite material involves preparing a sheet-like copper powder, nickel plating the graphene to obtain nickel-plated graphene, ball milling the flaky copper powder and nickel-plated graphene to obtain a mixed powder, subjecting the mixed powder to countercurrent rotation orientation treatment under a magnetic field to obtain a composite powder compact and sintering the composite powder compact. USE - Preparation of composite material. ADVANTAGE - The composite material has improved mechanical properties by undergoing sintering process, and utilizes graphene which is nickel-plated to increase the paramagnetism of graphene.
