Graphene coating for friction resistance reduction of solid interface and method thereof

The invention discloses a graphene coating for friction resistance reduction of a solid interface and a method thereof, and relates to the field of friction. Growing graphene on the growth substrate by adopting a chemical vapor deposition method to obtain a graphene-growth substrate composite material; acrylate is used as a protective layer to be spin-coated on the surface of the material, the growth substrate is removed after curing, a solid substrate is adopted to be attached to graphene floating on the liquid surface after the growth substrate is removed, transferring is completed, and a graphene-solid substrate layered structure is obtained; and removing the protective layer to finally obtain the graphene coating material. The prepared sample is fixed above and below a sliding friction tester to serve as a sliding friction side and a fixed friction side respectively, a face-to-face contact type friction testing method is carried out, finally, the average dynamic friction coefficient is calculated for eval
