%X Molybdate intercalated hydrotalcite/graphene oxide composite (HT-MoO4/GO) as corrosion inhibitor for carbon steel was synthesized and characterized. The influence of HT-MoO4/GO on corrosion resistance of waterborne epoxy coating applied on carbon steel was investigated. The results showed that hydrotalcite containing molybdate was formed on GO surface and the molybdate content in HT-MoO4/GO was 15.3%. HT-MoO4/GO provided both anodic and cathodic inhibition effects for carbon steel with an efficiency of 96%. The corrosion inhibition of HT-MoO4/GO depended not only on the inhibition effect of released molybdate but also on the deposition of HT-MoO4/GO particles on the steel surface. HT-MoO4/GO at 1 wt% concentration improved corrosion resistance of waterborne epoxy coatings. The presence of GO increased the effects of HT-MoO4 on protection properties of waterborne epoxy coatings.
