摘要

This report demonstrates what we did on graphene-based composites whose applications range from solid lubricants to supercapacitors to biomaterials. Graphene oxide (GO) and graphene nanosheets (GNS) could be used as a nano-scale reinforcements to increase hardness, to decrease friction coefficient and to reduce wear ratio of polymers and ceramics. Various kinds of graphene-based composites as electrode materials, such as graphene/conductive polymer, graphene/activated carbon fiber and graphene/metal oxide, all showed enhanced electrochemical properties compared with their unitary compounds. Graphene also was a very effective support for high-performance Pt-based catalysts in fuel cells. In addition, due to the excellent biocompatibility and antibacterial activity of GO sheets, they could be used for reinforcement in biocompatible scaffolds and antibacterial ? materials.
