Abstract
Reduced graphene oxide(rGO) has a lot of potential in the area of corrosion control of metals, because of its excellent barrier properties, dispersion capabilities, and impermeability. The current work hires on the corrosion resistance action of reduced graphene oxide(rGO) as an inhibitor for mild steel in simulated concrete pore solution. Here, three different nano rGO contained epoxy coatings were prepared by varying the percentage of rGO. The anticorrosion behaviour of rGO integrated epoxy composite coating was evaluated using open circuit potential and polarization studies. The results indicated that rGO nanoparticles were properly distributed in the epoxy coating and showed excellent barrier properties. Moreover, anti-corrosion processes for composite coatings improved by the addition of various percentages of rGO were apparently hypothesized, implying that epoxy coating containing 1.0 wt.% rGO showed better corrosion resistant behaviour in concrete pore solution medium containing 0.5M NaCl solution.
