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.

合成并表征了钼酸盐插层水滑石/氧化石墨复合物（HT-MoO ₄ / GO）作为缓蚀剂。研究了HT-MoO ₄ / GO对碳钢水性环氧涂料耐蚀性的影响。结果表明，GO表面形成了含钼酸盐的水滑石，HT-MoO ₄ / GO中钼酸盐的含量为15.3％。HT-MoO ₄ / GO为碳钢提供了阳极和阴极抑制作用，效率为96％。HT-MoO ₄ / GO的腐蚀抑制不仅取决于释放的钼酸盐的抑制效果，还取决于HT-MoO ₄的沉积。/ GO颗粒在钢表面上。浓度为1 wt％的HT-MoO ₄ / GO改善了水性环氧涂料的耐腐蚀性。GO的存在增加了HT-MoO ₄对水性环氧涂料保护性能的影响。
