▎ 摘　　要

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.
