Abstract
The tribological properties of the graphene/C60/graphene sandwich structure are investigated by molecular dynamics simulations. Friction coefficients are calculated for the sandwich structure, composed of graphene layers and a single C60 film layer, i.e. a {111} monolayer of a C60 face centered cubic crystal. The effect of surface roughness on the tribological properties is considered explicitly by coating a diamond surface with three different surface roughness values, 0 Å, 2.5 Å and 5 Å. Results indicate ultra-low friction coefficients for the sandwich structure in all cases. The friction coefficients predicted are μ < 0.01, for load pressure in the range of 1–8 GPa. The sandwich structure synergizes the outstanding strength and low friction coefficient of graphene with the nanobearing properties of C60 molecules. These simulation results suggest that the graphene/C60/graphene sandwich structure provide an ultra-low friction, strong, and wear resistant coating for realistic (rough) surfaces.
