Abstract

The invention provides a metal-graphene composite material and a preparation method thereof, and relates to the technical field of electronic equipment. Composite particles with metal particles as inner cores and graphene layers as shells are doped in molten metal, and forming treatment is carried out. According to the invention, the metal particles are used as the inner core, the graphene layer is used as the shell, when the composite particles are used as an integral structure, the density of the integral structure is adjusted through the mass of the metal particles, and the influence of large density difference between the graphene and the metal on non-uniform distribution of the graphene in the metal can be reduced.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a metal-graphene composite material and a preparation method thereof. Background technique [0002] In order to reduce the resistance of the wire to reduce the thermal effect during the electrification process, the composite of graphene and metal can improve the electrical conductivity of the metal, which will bring great economic benefits. [0003] Common graphene and metal composites have the following several methods: one is to blend the metal and graphene powder and then melt it into shape, the other is to coat the metal wire with a graphene layer, and the third is to add metal and graphene to the organic system. Graphene, a finely regulated mixture of metal and graphene during the crystallization of the metal. However, these methods all have the problem of uneven distribution of graphene.
