    • Abstract
  • Tetrahydrofuran(THF) as dispersant and 2-methylimidazole as catalyst curing agent were mixed into graphene oxide(GO) dispersion system, which then was blended into silicone modified epoxy resin to obtain new anticorrosion coating. The corrosion resistance of the coating was analyzed by open circuit potential(OCP) and Tafel curve. The results show that the compund coatings containing graphene oxide present better corrosion resistance than epoxy resin coatings, and the addition of graphene oxide not only promotes the barrier of the coatings, but also changes the corrosion environment. Among several kinds of epoxy resin coatings, the epoxy resin coatings with 5%(w) graphite oxide have the best corrosion resistance, with lower corrosion current and the highest corrosion potential.
