Abstract

Abstract Coatings based on a graphene oxide–boron nitride/epoxy (GO–BN/EP) system were fabricated and applied for corrosion protection of metal substrates. GO–BN hybrid sheet synthesized by using a modified Hummers’ method had a higher lipophilicity than GO and BN. Then, GO–BN hybrid was incorporated into an epoxy coating to investigate the compactness and the corrosion protection ability of GO–BN hybrid/epoxy coating for metal substrates. The results show that GO–BN hybrid presents a desirable dispersibility in epoxy coating, exhibiting an outstanding barrier property for corrosive ions in a 3.5 wt% NaCl solution among the four systems under investigation. The present study set forth an innovative method to synthesize GO–BN hybrid in the field of corrosion protection.
