摘要：
The hybrid coatings based on graphene oxide-zirconia dioxide/epoxy (GO-ZrO2/EP) system were fabricated and applied for corrosion protection of metal substrate. First, GO-ZrO2 hybrid was synthesized through two different silane coupling agents and the morphology and structure were confirmed by Field emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis. Then, GO-ZrO2 was incorporated into EP to investigate the corrosion protection of metal substrate. Investigations revealed that the corrosion protective properties were significantly enhanced by the addition of GO-ZrO2 to EP. The enhancement attributed to the sheet like structure, uniform dispersion and exfoliation of GO-ZrO2 hybrid within EP matrix, which effectively prevented the underlying metal substrate from corrosion attack.
