Waterborne　epoxy　(WEP)　resins　have　garnered　significant　interest　due　to　their　potential　application　as　anticorrosion　coatings　for　steel　materials.　However,　it　has　been　reported　that　defects　in　the　cured　coatings　generated　during　the　curing　process　lead　to　the　level　of　anticorrosion　not　meeting　the　expected　effects.　In　this　study,　TiO2　and　GO　were　selected　to　be　modified　by　polyvinylpyrrolidone　(PVP)　to　obtain　PT　and　PG,　and　used　to　improve　the　anticorrosion　performance　of　WEP.　The　obtained　PT　and　PG　were　characterized　using　Fourier　transform　infrared,　Raman,　and　x-ray　photoelectron　spectroscopy.　The　morphology　of　PT　and　PG　before　and　after　modification　was　observed　using　scanning　electron　microscopy,　and　the　differences　were　described.　The　analysis　results　of　laser　confocal　scanning　microscopy　and　water　contact　angle　(WCA)　indicate　that　there　are　differences　in　surface　roughness　and　WCA　of　the　WEP　coatings　with　or　without　PT　and　PG.　Electrochemical　impedance　spectroscopy　was　used　to　evaluate　the　anticorrosion　performance　of　the　coatings.　The　results　showed　that　WEP　coatings　containing　PT　and　PG　exhibited　better　anticorrosion　performance.　The　synergistic　enhancement　of　PT　and　PG　on　the　anticorrosion　performance　was　proposed,　which　can　be　attributed　to　the　comprehensive　effect　of　the　hydrophobicity　of　the　coating　surface　and　the　barrier　effect　of　PT　and　PG　within　the　coatings.
