摘要：
An amino functionalized graphene oxide (FGO) was synthesized and characterized by Fourier transform infrared spectroscopy (FTIR) and X-Ray diffraction analysis (XRD). Then, FGO/epoxy composite was prepared through dispersing 0.1 wt.% of FGO in an epoxy coating through wet transfer method (WTM). The GO/epoxy and FGO/epoxy composites were applied on the mild steel substrates and their barrier and corrosion protection performance were characterized by salt spray test and electrochemical impedance spectroscopy (EIS). Incorporation of 0.1 wt.% of FGO nanosheets into the epoxy coating significantly enhanced the corrosion resistance of the coating through improving its ionic resistance as well as barrier properties.
