Poor anti-wear of the organic coatings severely affected their applications in engineering and technology fields. In this work, aniline oligomer grafted graphene oxide (GO) was used to improve the wear and corrosion per-formance of phenoxy-resin coating (aniline oligomer: AO; GO grafted by aniline oligomer: AOFG; phenoxy-resin: PHE). The wear and corrosion protection performance of the composite coatings was significantly improved compared with pure PHE coating because of the enhanced dispersibility of GO in organic matrix, and hydrogen bonds were formed between the grafted aniline oligomer on the GO surface and PHE. As the result, the coating densities and mechanical properties were significantly improved under enhanced interfacial strength between AOFG and PHE. In addition, the wear rate of AOFG/PHE coating decreased by 81 %, and the impedance modulus increased by five orders of magnitude compared to the pure PHE coating after 120 h of immersing. The wear mechanism and corrosion protection mechanism of the AOFG/PHE coating were also discussed.
