To　promote　the　anticorrosion　performance　of　epoxy/zinc　(EP/Zn)　coating,　graphene　oxide　(GO)　was　directly　incorporated　into　dual-component　paint.　Interestingly,　it　was　found　that　the　method　of　incorporating　GO　during　the　fabrication　of　the　composite　paints　strongly　influenced　their　performance.　The　samples　were　characterized　by　Fourier　transform　infrared　spectroscopy　(FT-IR),　X-ray　diffraction　(XRD),　and　Raman　spectroscopy.　The　results　indicated　that　GO　could　be　intercalated　and　modified　with　the　polyamide　curing　agent　while　preparing　component　B　of　the　paint,　for　which　the　interlayer　spacing　of　the　resulting　polyamide　modified　GO　(PGO)　increased,　and　its　dispersion　in　organic　solvent　was　improved.　The　corrosion　resistance　of　the　coatings　was　studied　through　potentiodynamic　polarization　testing,　electrochemical　impedance　spectroscopy　(EIS),　and　immersion　testing.　Among　the　three　types　of　as-prepared　coatings,　i.e.,　neat　EP/Zn　coating,　GO　modified　EP/Zn　coating　(GO/EP/Zn),　and　PGO-modified　EP/Zn　coating　(PGO/EP/Zn),　the　order　of　the　corrosion　resistance　of　the　coatings　was　PGO/EP/Zn　＞　GO/EP/Zn　＞　neat　EP/Zn.　This　work　demonstrates　that　although　the　in　situ　modification　of　GO　with　a　curing　agent　is　a　simple　method,　it　evidently　promotes　the　shielding　effect　of　the　coating　and　enhances　its　corrosion　resistance.
