Problems solved by technology

However, since the reduction effect of GO is limited by the copper matrix, the oxygen content in the copper-graphene composite phase obtained by this method is high, resulting in a composite phase with lower resistivity than copper foil
In addition, the reduction process of GO involves complex processes such as high temperature, and the reduction process will have a certain impact on the formation of the final copper-graphene composite phase, resulting in poor controllability of the process.

Abstract

The invention discloses a preparation method of a copper-graphene complex phase. The preparation method comprises the following steps of: (1) removing oxides from the surface of a base plate by using hydrochloric acid; (2) preparing copper sulfate, sulfuric acid, the hydrochloric acid and a surfactant into a copper plating solution; (3) adding a graphene nanosheet to the copper plating solution to obtain a plating solution which contains the graphene nanosheet; and (4) placing a phosphorus copper sheet serving as an anode and the base plate serving as a cathode into the plating solution for plating to obtain the copper-graphene complex phase. The preparation method disclosed by the invention prevents the GO reduction process of the traditional method by directly compounding graphene and copper and therefore has the advantages of simple process, good controllability and wide application range; the prepared copper-graphene complex phase has good electrical property, antioxidation property, mechanical property and anti-corrosive property.

Description

technical field [0001] The invention relates to a preparation method of copper-graphene composite phase. Background technique [0002] Graphene has extremely high carrier mobility, thermal conductivity, and oxidation resistance. Combining graphene with copper can not only improve the electrical and thermal conductivity of copper, but also improve the oxidation resistance of copper. [0003] The existing copper-graphene composite phase is to combine graphene oxide (GO) with copper, and then reduce GO to graphene to obtain copper-graphene composite phase. However, since the reduction effect of GO is restricted by the copper matrix, the oxygen content in the copper-graphene composite phase obtained by this method is high, resulting in a lower resistivity of the composite phase than that of copper foil. In addition, the reduction process of GO involves complex processes such as high temperature, and the reduction process will have a certain impact on the formation of the final ...
