The role of interfacial thermal (Kapitza) resistance on the heated evaporation rates of water thin films over nanostructured graphene-coated surfaces is investigated. The Kapitza resistance between graphene and water, when the graphene flakes are parallel (phi = 0 degrees) and perpendicular (phi = 90 degrees) to the interface, are calculated using molecular dynamics simulations. The hydrophilicity of graphene when phi = 0 degrees leads to enhanced liquid layering adjacent to the surface resulting in a lower Kapitza resistance relative to the phi = 90 degrees case. The predicted evaporation rate on phi = 0 degrees surface is relatively higher than for the phi = 90 degrees surface due to an enhanced heat transfer between the substrate and water thin film. Results from our simulation aid in understanding the role of Kapitza resistance on heated evaporation rates, and suggest a possibility of engineering interfaces with tunable evaporation rates using nanostructured graphene coating.
