Advances in Epoxy-based Nanocomposite Superhydrophobic Anti-corrosion Coatings
Epoxy resin has excellent acid and alkali resistance,electrical insulation,and strong mechanical properties,has strong adhesion with various substrates.and is widely used in the field of anti-corrosion.Introducing superhydrophobicity into epoxy-based anticorrosion coatings to obtain epoxy-based nanocomposite superhydrophobic anticorrosion coatings can reduce the direct contact between the coating and the corrosive environment,thus improving the durability of the coating.This paper mainly reviews the research progress of epoxy-based nanocomposite superhydrophobic anticorrosive coatings at home and abroad in recent years,including the anticorrosive principle of the coatings,the preparation method and the practical application,and finally looks forward to its development prospect.
