NOVELTY - Preparing copper-graphene composite material involves mixing graphene dispersion, copper-based material powder, polyacrylamide gel and water to obtain ball milling material. The polyacrylamide solution is added to ball milling material and deairing to obtain mud, The mud is dried and crushed to obtain powder. The powder is added in mold and cold pressed to obtain blank. The blank is treated at 450-600 degrees C and element is diffused uniformally. The reaction mixture is treated at 800-1000 degrees C and cooled to obtain pre-sintering body. The pre-sintering body is used to obtain green compact. USE - Method for preparing copper-graphene composite material (claimed). ADVANTAGE - The method enables to prepare copper-graphene composite material in simple and cost effective manner that has enhances interface bonding force, excellent performance, reduces stress concentration, is good for preventing crack.
