Problems solved by technology

However, the solubility of graphene in metallic copper is low, and there is neither diffusion nor reaction between the adjacent interfaces of graphene and metallic copper. The wettability of metallic copper to graphene is poor, and the aspect ratio of graphene is 100-1000. High surface free energy, easy to agglomerate, and difficult to disperse uniformly in the composite matrix, these factors seriously restrict the development of graphene-reinforced copper-based composites

Abstract

The invention relates to a zero emission and pollution-free graphene chemical copper plating method. The chemical reaction shown as the specification is carried out to realize rapid and efficient chemical copper plating of graphene. After chemical copper plating on a graphene surface, the agglomeration of graphene is greatly lowered, the copper plated layer is uniform and dense, and is combined with the matrix firmly, thus effectively improving the interface wettability of graphene and the copper matrix, strengthening the interface bonding of a graphene reinforcement phase and the copper matrix, and greatly improving the properties of the graphene reinforced copper matrix composite material. In addition, the graphene copper plating method has the advantages of plating solution recyclability, no waste or pollutant emission, and ecological environmental protection.
