▎ 摘　　要

NOVELTY - Preparing high conductive nickel-modified graphene/copper composite material involves (a) loading nickel on the graphene to obtain nickel-graphene powder using two-step hydrothermal method, (b) mixing the nickel-graphene powder with the copper powder, and ball milling to obtain a mixed powder and (c) sintering the mixed powder to obtain the final product. USE - Preparing the high conductive nickel modified graphene/copper composite material is used in conductive field, copper and copper-based composite material. ADVANTAGE - The method has simple operation, no pollution and low cost and overcomes the high production cost of preparing nickel modified grapheme by using chemical vapor deposition method in the existing technology. The obtained composite material has thermal conductivity that is better than pure copper, especially the high temperature conductivity is good, and the conductivity of nickel modified graphene in the composite material in a certain range is higher than that of pure copper. The metal nano-particle innovative load on the graphene, for modified graphene, so as to enhance the combination property of graphene and copper, improving wetting ability of copper and graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high conductive nickel modified graphene/copper composite material.
