▎ 摘　　要

NOVELTY - Preparing graphene/copper powder material comprises (1) adding copper powder to the fluidized bed, (2) decomposing the gas phase carbon source into the hydrocarbon bed through the methane cracking device of the fluidized bed, and then passing into the fluidized bed, (3) introducing fluidizing gas into the fluidized bed and fluidizing the copper powder, and (4) growing graphene at a low temperature on the surface of the copper powder fluidized in the fluidized bed under the action of the hydrocarbon atom and the fluidizing gas to obtain a graphene/copper powder material. USE - The method is useful for preparing graphene/copper powder material. ADVANTAGE - The graphene/copper powder material: has good overall performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene/copper powder material.
