Anti-corrosion performance of a vinyl ester resin coating was enhanced by intercalation of MXene nanosheets in the resin matrix through wet transfer method. Open circuit potential and electrochemical impedance spectroscopy tests was executed to evaluate the barrier and corrosion protection performance of the VER and MXene/VER composite coatings. The results revealed significant enhancement of the corrosion protection performance of the MXene/VER composite coating samples compared with that of the VER coating samples. The real impendence values of VER and MXene/VER composite coatings was 1.83 and 5.87 MΩ cm2, and the coating resistance was 1.72 and 5.74 MΩ cm2 after 40-days soaking in the 3.5 wt % of NaCl solution, respectively. The results indicate that the 0.1 wt % MXene/VER composite coating exhibited a significant improvement of coating resistance and real impendence by up to 320% and 330%, respectively. The impermeability makes the 2D MXene nanosheets acting as a good barrier to corrosive electrolyte, leading to a more tortuous diffusion pathway and enhanced corrosion protection performance.
