Abstract The silane coupling agent functionalized graphene oxide (KGO) was prepared using a simple one-step hydrothermal method and combined it with epoxy resin to synthesize a high-performance anticorrosive coating. KGO was characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD). Epoxy resin composite coatings with 0.1%, 0.2%, and 0.3% KGO (KGO/EP) were prepared and their corrosion resistance was characterized by electrochemical impedance spectroscopy (EIS) and salt spray test. The results reveal that the shielding and corrosion resistance of epoxy resin composite coating are improved significantly by KGO. The corrosion current density decreases from 8.8×10^-8 A·cm^-2 to 2.0×10^-8 A·cm^-2, the impedance modulus (｜Z｜_{0.01 Hz}) of 0.2 KGO/EP remains at a relatively high value after 72 h of immersion in 3.5% NaCl, which is about two order higher than that of GO/EP. When the mass fraction of KGO in the KGO/EP composite coating is 0.2%, the corrosion resistance of the coating is optimal.
