Abstract
The invention discloses a graphene composite material and a production process thereof, wherein the graphene composite material comprises a substrate, and a graphene layer and a metal nanometer particle layer alternately deposited on the surface of the substrate. The composite material designed and prepared based on an ultrafine spraying process is ultrahigh in strength, excellent in surface lubricity and easy to cover any substrate surface, and can serve as an excellent interface material to effectively prevent the material and energy loss caused by friction. Compared with other graphene composite material production process, the spraying process is simple and convenient, wide in application range and capable of guaranteeing whole uniformity of the composite material when effectively controlling double-component ratio, so that the composite material is higher in practical value.
