摘 要:Graphene(G) was dispersed uniformly in water and used as an inhibitor in waterborne epoxy coatings.The effect of dispersed G on anticorrosion performance of epoxy coatings was evaluated.The composite coatings displayed outstanding barrier properties against H2O molecule compared to the neat epoxy coating.Open circuit potential(OCP),Tafel and electrochemical impedance spectroscopy(EIS)analysis con-?rmed that the corrosion rate exhibited by composite coatings with 0.5 wt%G was an order of magnitude lower than that of neat epoxy coating.Salt spray test results revealed superior corrosion resistance offered by the composite coating.
