摘要：

Protecting the surface of metals such as Fe and Cu from oxidizing is of great importance due to their widespread use. Here, oxidation resistance of Fe and Cu foils was achieved by coating them with reduced graphene oxide (rG-0) sheets. The rG-0-coated Fe and Cu foils were prepared by transferring rG-0 multilayers from a SiO2 substrate onto them. The oxidation resistance of these rG-0-coated metal foils was investigated by Raman spectroscopy, optical microscopy, and scanning electron microscopy after heat treatment at 200 degrees C in air for 2 h. The bare metal surfaces were severely oxidized, but the rG-0-coated metal surfaces were protected from oxidation. This simple solution process using rG-0 is one advantage of the present study.
