Preparation of epoxy nanocoatings based on magnetic graphene containing nickel and cobalt metal nanoparticles with high resistance, anti-corrosion, and water resistance for industrial use

The advances achieved in nanotechnology have brought significant changes in the coating and formulating processes, which have created practical applications in dealing with fire, corrosion, impact, heat, wear, wear and tear and other environmental factors. In this context, it is possible to control indicators such as size, chemical properties, surface protection, activity, and reactivity of nanoparticles. The application of nanocoatings in steel structures in light and heavy industries and marine is determined according to their specific design and the properties resulting from this structure. The aim of the present research work is to prepare epoxy nano-coatings based on graphene composite to prevent the corrosion of steel. Graphene oxide was first synthesized by the modified Hamer method to prepare these compounds. Then, by using iron, nickel and cobalt metals, the desired composite was prepared and identified using FTIR, FESEM, XRD, EDX, TGA and DSC analyses. TOEFL curves were used to check and evaluate the resistance of the prepared coating and its components against corrosion.
