Composite coatings were fabricated based on a graphene oxide–metal oxide/urushiol formaldehyde polymer (GO–TiO₂/UFP, GO–SiO₂/UFP and GO–Y₂O₃/UFP) system with modifications, and its effectiveness in corrosion protection of metal substrates was demonstrated. First, a GO–TiO₂ composite was synthesized using titanium dioxide loading on GO via 3-aminopropyltriethoxysilane (APTES). The GO–Y₂O₃ composite was synthesized using nano-yttrium oxide intercalating into GO through two different silane coupling agents. The GO–SiO₂ composite was synthesized via an in-situ two-step sol-gel process utilizing APTES and tetraethylorthosilicate (TEOS) in an aqueous ethanol solution. The morphology and structure of the GO–metal oxide composites (GO–TiO₂, GO–Y₂O₃ and GO–SiO₂) were studied. Subsequently, GO–metal oxides were incorporated into UFP to investigate the composite’s effectiveness in corrosion protection of metal substrates. Compared with GO–TiO₂/UFP and GO–Y₂O₃/UFP, GO–SiO₂/UFP showed superior alkali-resistance enhancing performance. Additionally, GO crosslinked with APTES–TiO₂ via covalent bonds and the well-dispersed GO–TiO₂ in UFP improved the electrochemical corrosion properties of the UFP coatings, most likely due to the obstruction of the diffusion pathways inside the UFP coating matrix, thus preventing the diffusion of penetrating species. It was revealed that the corrosion resistance of GO–TiO₂/UFP composite coating was noticeably higher than GO–SiO₂/UFP and GO–Y₂O₃/UFP composite coatings.

基于氧化石墨烯-金属氧化物/漆酚甲醛聚合物（GO-TiO ₂ /UFP、GO-SiO ₂ /UFP 和 GO-Y ₂ O ₃ /UFP）系统制备复合涂层，并进行了修改，及其在腐蚀保护方面的有效性证明了金属基板的性能。首先，通过 3-氨基丙基三乙氧基硅烷 (APTES) 在 GO 上负载二氧化钛合成了 GO-TiO ₂复合材料。GO-Y ₂ O ₃复合材料是使用纳米氧化钇通过两种不同的硅烷偶联剂嵌入到GO 中合成的。GO-SiO ₂复合材料是通过原位两步溶胶-凝胶法在乙醇水溶液中使用 APTES 和原硅酸四乙酯 (TEOS) 合成的。研究了GO-金属氧化物复合材料（GO-TiO ₂、GO-Y ₂ O ₃和GO-SiO ₂）的形貌和结构。随后，将 GO 金属氧化物加入 UFP 以研究复合材料在金属基材腐蚀保护中的有效性。与GO-TiO ₂ /UFP 和GO-Y ₂ O ₃ /UFP 相比，GO-SiO ₂ /UFP 显示出优异的耐碱性增强性能。此外，GO通过共价键和分散良好的 GO-TiO与 APTES-TiO ₂交联UFP 中的₂改善了 UFP 涂层的电化学腐蚀性能，这很可能是由于 UFP 涂层基体内部的扩散路径受阻，从而阻止了渗透物质的扩散。结果表明，GO-TiO ₂ /UFP 复合涂层的耐腐蚀性能明显高于GO-SiO ₂ /UFP 和GO-Y ₂ O ₃ /UFP 复合涂层。
