摘要

Epoxy coatings and Reduced Graphene Oxide (RGO) modified epoxy coatings were prepared on N80 tubing steel. The influence of temperature on the corrosion resistance of RGO modified epoxy coatings was studied. And the corrosion behavior of epoxy coatings and RGO modified epoxy coatings in 10.0 wt% NaCl solution at different temperatures was compared. The results showed that the corrosion resistance of both coatings decreased with the increase of temperature. However, the corrosion resistance of RGO modified epoxy coating was two to three orders of magnitude higher than that of epoxy coating at different test temperature. The addition of RGO nanosheets greatly enhanced the corrosion resistance of epoxy composite coatings in 10.0 wt% NaCl solution at high temperature due to their high impermeability and negative coefficient of thermal expansion.
