The protection of metals such as Fe and Cu, which are widely used in industry, is of great importance because of necessity to preserve their surface properties. Traditional protection methods may lead to negative influences on physical property and surface deformation. In this study, we demonstrate oxidation resistance of Fe and Cu foils by coating them with reduced graphene oxide (rGO) sheets. The rGO-coated Fe and Cu foils were prepared by transferring rGO multilayers on SiO2 substrate to Fe and Cu foils. The oxidation resistance of the rGO-coated metal substrates was investigated by Raman spectroscopy and scanning electron microscopy after heat treatment at 200 oC in air for 2 h. The bare metal surfaces were severely oxidized, whereas the rGO-coated metal surfaces were protected from oxidation. The results indicate that the rGO thin film plays a role as an oxidation-resistive barrier. The simple solution process using rGO is the advantage of the present study
