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 blank polyurethane coating and coating containing GO by electrochemical impedance spectroscopy. The results showed that GO-CR has 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.</p>}, number={3}, journal={Vietnam Journal of Science and Technology}, author={Nguyen, Thuy Duong and Tran, Boi An and Phan, Thanh Thao and Vu, Ke Oanh and Nguyen, Anh Son and Nguyen, Tuan Anh and Thi Xuan Hang, To}, year={2020}, month={May}, pages={274–281} }
