In this paper the anticorrosive properties of the few-layer graphene nanostructures were investigated. On the surface of copper and nickel plates the few-layer graphene nanostructures were formed using the CVD (chemical vapor deposition) method. After that, these plates were exposed to the temperature in the air atmosphere. The results of elemental analysis, performed by the EDS (energy dispersive spectroscopy) method showed that the few-layer graphene coated metal plates proved to be more resistant to oxidation than bare metal plates. In addition, we presented computer models and theoretical calculations of the studied systems, performed by the DFT (density functional theory) and MD (molecular dynamics) methods. These results combined with experimental data show the high effectiveness of the protective action of the few-layer graphene against metal corrosion.
