Mechanical response of few-layer graphene films on copper foils

Few-layer graphene (FLG) continuous films were synthesized on copper foils using atmospheric pressure chemical vapour deposition and their mechanical behaviour is examined using nanoscratch tests. This study investigates how the FLG films respond to a range of applied loads. The FLG films are polycrystalline with 2 micron domains, which fragment upon nanoscratching. Using nanoscratch tests, it is possible to gauge an understanding of the interaction of the FLG with the varying copper grain boundaries across the copper foil.
