The graphene oxide (GO) was obtained by Hummers' method using natural graphite as raw materials. Then, the GO/poly(methyl methacrylate) (PMMA) nanocomposites were prepared by in situ polymerization. The tribological and electrical properties of nanocomposites were studied. As a result, the frictional coefficient of GO/PMMA nanocomposites was prominently improved with the content of the graphene oxide increasing. The electrical properties of nanocomposites were slightly increased when adding the graphene oxide.
