The advances achieved in nanotechnology have brought significant changes in coating processes and formulation of coating materials, which have created effective applications in dealing with fire, corrosion, impact, heat, and other environmental factors. New coatings prepared based on nanoparticles have found a variety of applications, including protection against corrosion, light, wear and tear resistance, and swelling coatings. The advances in the formulation of these materials allow the control of parameters such as the size of nanoparticles, and chemical properties. The present research aims to prepare graphene composite coatings to prevent steel corrosion. Graphene oxide was first synthesized by the modified Hamer method, and then, the desired composite was prepared using the desired metals. Finally, the effect of each composite component on the corrosion of steel was investigated. Next, the effect of graphene composite on preventing corrosion was studied. Next, the hydrophobicity of the surface of steel coated with epoxy resin containing graphene composite and without coating and the size of nanoparticles by SEM was investigated. A potentiostat-galvanostat device equipped with a three-electrode was used for electrochemical corrosion measurements and so Tafel polarization technique was used to evaluate corrosion.
