▎ 摘　　要

NOVELTY - Method for preparing copper-tungsten graphene-containing composite material involves (a) preparing tungsten with copper and graphene core-shell powder, and (b) sintering the tungsten with copper and graphene core-shell powder prepared in step (a) to obtain a copper-tungsten and graphene composite material. USE - The method is used for preparing copper-tungsten composite material used as main switch electric appliance of medium-high voltage electric network and electrified railway. ADVANTAGE - The method solves the problem that the tungsten skeleton strength and conductivity of the copper-tungsten composite material is influenced by the addition of the graphite, and the method for preparing the composite material has low cost, and has good anti-arc ablation performance. The method uses graphene oxide after electrochemical reduction in the electro-deposition process of graphene oxide, which greatly reduces the production cost.
