▎ 摘　　要

NOVELTY - Preparing graphene powder coated with metal involves filtering metal particles with uniform particles filter and performing corona treatment on the surface of the metal particles, uniformly mixing the corona treated metal particles surface with graphene powder to prepare metal particles and graphene powder, (c) placing the mixed powder into the 1060-1500℃ high-temperature furnace, keeping the vacuum environment in the furnace, annealing for 15-35 minutes, keeping the temperature and vacuum environment of the high temperature furnace, and introducing the growth atmosphere into the vacuum for 35-180 minutes, and taking out the mixture and separating the mixture after slowly cooling to room temperature by the high heat furnace. USE - Preparation method of graphene-coated metal particles used in industry. ADVANTAGE - The graphene powder is pre-mixed with the metal particles, so that the graphene powder can avoid the problem of metal particles adhered between metal particles in the growth process. The metal particles are pre-corona processed, so as to be convenient for the surface growth of graphene. The method is simple and convenient to use.
