Abstract
The invention provides a preparation method of a copper-based graphene composite material. The preparation method of the copper-based graphene composite material comprises the following steps: pretreating an original plate-shaped copper base by an electrochemical polishing process to obtain a pretreated copper base, wherein the thickness of the original plate-shaped copper base is 5 to 25 microns;growing graphene on the upper surface and the lower surface of the pretreated copper base by a chemical vapor deposition process to obtain graphene coated copper bases; and performing hot pressed sintering treatment on at least one graphene coated copper base to obtain the copper-based graphene composite material, wherein the copper-based graphene composite material is a layered composite material formed by alternately compounding graphene and the copper base, and the copper base is in a single crystalline state in the thickness direction of the copper-based graphene composite material and takes on predominant crystal orientation (111). By the preparation method of the copper-based graphene composite material provided by the invention, the copper-based graphene composite material with high conductivity can be prepared.
Description
Technical field [0001] This application relates to the technical field of composite materials, in particular to a method for preparing a copper-based graphene composite material and a copper-based graphene composite material. Background technique [0002] In recent years, with the rapid development of modern technology, the performance requirements of copper-based composite materials have become higher and higher, for example, the electrical conductivity is required to be higher than that of pure silver. The extremely high conductivity and electron mobility of graphene make it possible for the conductivity of copper-based composites to reach pure silver. [0003] At present, the solid carbon source is usually dispersed on the surface of spherical copper powder, and then the solid carbon source is converted into graphene grown along the surface of the spherical copper powder by chemical vapor deposition technology to obtain graphene-copper composite powder, and then hot pressing Th...
