NOVELTY - Preparing graphene-coated metal particle composite material involves mixing metal particles and graphene powder uniformly to make a mixed powder, placing mixed powder in a high temperature and vacuum environment, introducing carbon source and growth atmosphere into a high temperature and vacuum environment, and adjusting pressure of the vacuum environment to grow and repair graphene, cooling down the high temperature and vacuum environment under vacuum, and taking out the mixed powder after growth under vacuum or non-vacuum environment, and separating taken out mixed powder to obtain a graphene-coated metal particle composite material and the remaining graphene powder. USE - Method for preparing graphene-coated metal particle composite material. ADVANTAGE - The method enables to prepare graphene-coated metal particle composite material, which avoids adhesion of metal particles during growth, and improves quality of graphene coated on the surface of metal particles and is easier to separate.
