Abstract:
We report the characterisation of exfoliated few layer graphene (FLG) flakes using a range of scanning probe techniques. We have examined the nanoscale mechanical and interfacial properties of FLG and its substrate material, SiO2, in air, polar liquid (water) and non-polar liquid (dodecane) environments. We present analysis of absolute adhesion and relative friction between SPM probe and FLG and examination of surface and subsurface nanoscale structure. The understanding of the modification of the interaction of supported graphene due to different liquid environments is essential for the development of real graphene based devices e.g. rechargeable batteries, supercapacitors and displays.
