SEM images of the stainless steel surface: after mechanical polishing (a); after successful graphene transfer (b); AFM images of graphene coated steel (G-316-L): height image (c) and phase image (d). Figures 2(c) and 2(d) present AFM images of steel surface coated with graphene. The surface roughness was investigated and the surface profile in the selected cross-section and the average analyzed height of the film were determined.
