Abstract: | Curcumin modified graphene oxide (GO-CR) was prepared using the adsorption method and polyurethane (PU) coating containing 0.3 wt% GO-CR was prepared on carbon steel. Synthesized GO-CR was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and zeta potential measurement. Corrosion protection property of polyurethane coating containing GO-CR was evaluated and compared with that of blank polyurethane coating and coating containing GO by electrochemical impedance spectroscopy. The results showed that GO-CR has a layer structure like GO with lower crystallinity. In GO-CR, structure curcumin was attached on GO surface. The presence of curcumin on GO-CR surface provided corrosion inhibition action for PU coating and also improved the dispersion of GO in PU coating. |
