Abstract: In this work, graphene oxide (GO) was prepared by modified Hummers method. Polyurethane coatings with different GO concentrations (0.1-0.5 %) were prepared for corrosion protection of carbon Steel. Synthesized GO was characterized by FTIR and XRD. Corrosion resistance of polyurethane coatings containing GO was investigated by electrochemical impedance spectroscopy and salt fog test. The effects of GO on protection performance of polyurethane coatings depended on its dispersion ability. GO at a concentration of 0.1 % significantly improved corrosion resistance of polyurethane coatings.
