Realising the potential of graphene-based materials for biosurfaces – A future perspective

Recently, the promising mechanical, tribological and biomedical properties of graphene and its derivatives (mainly graphene oxide and reduced graphene oxide) and graphene-reinforced nanocomposites have attracted great attention of tribologists, biomedical researchers and clinical doctors. In this paper, the tribology and biocompatibility of graphene-based materials are reviewed first to serve as a basis for the succeeding discussion. Then the current status of biosurface engineering with graphene-based materials and graphene-reinforced nanocomposites is overviewed. Finally, the potential of graphene-based materials for biosurfaces is discussed and the future directions are recommended.
