There has been an ongoing effort by the coatings industry to improve surface properties in order to increase corrosion and wear resistances, as well as other material properties. In this work, we report a methodology for producing nanocomposite films of polyurethane and graphene oxide and polyurethane and reduced graphene oxide. The coatings were applied on steel. The nanocomposites coatings were characterized by optical microscopy, scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, contact angle measurements, and electrochemical impedance spectroscopy. Corrosion tests reveal that the use of reduced graphene oxide increases corrosion resistance when compared with the use of graphene oxide as filler.
