MXenes are a unique family of two-dimensional (2D) transition metal carbides and/or nitrides, which have been proven useful for energy storage, water purification, and biomedical applications. Herein, a kind of heterojunction structure was designed by grafting highly conductive MXene (Ti₃C₂) on the graphene oxide (GO) nanosheets， which was confirmed by Fourier transform infrared (FT-IR) spectroscopy, X-ray photoelectronic spectroscopy (XPS) and Raman results. Open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and salt spray measurements corroborated that inclusion of 0.5 wt% Ti₃C₂ or GO-Ti₃C₂ into epoxy zinc-rich coating (ZRC) effectively enhance the cathodic protection capability. Additionally, superior corrosion resistance was achieved by incorporation of GO-Ti₃C₂ into ZRC since GO-Ti₃C₂ in the coating improved the utilization rate of zinc particles and GO provided barrier protection for inhibiting the diffusion of corrosive agents. At the end of immersion, R_c value of ZRC/GO-Ti₃C₂ coating was 3.047 × 10⁴ Ω·cm², which was one order of magnitude higher than that of ZRC coating. Scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS) measurements demonstrated that ZRC/GO-Ti₃C₂ coating exhibited lower speed of zinc particles oxidation and intact steel substrate. Hence, ZRC/GO-Ti₃C₂ coating exhibited the optimal corrosion resistance among the four kinds of coatings.

MXene是独特的二维（2D）过渡金属碳化物和/或氮化物族，已被证明可用于能量存储，水净化和生物医学应用。在本文中，通过将高导电性MXene（Ti ₃ C ₂）接枝在氧化石墨烯（GO）纳米片上，设计了一种异质结结构，这通过傅里叶变换红外光谱（FT-IR），X射线光电子能谱（XPS）得以证实。 ）和拉曼结果。开路电势（OCP），电化学阻抗谱（EIS）和盐雾测量结果证实了包含0.5 wt％的Ti ₃ C ₂或GO-Ti ₃ C ₂制成环氧富锌涂层（ZRC）可有效增强阴极保护能力。另外，通过将GO-Ti ₃ C ₂掺入到ZRC中获得了优异的耐腐蚀性，这是因为涂层中的GO-Ti ₃ C ₂改善了锌颗粒的利用率，并且GO为抑制腐蚀剂的扩散提供了屏障保护。在浸泡结束时，R _Ç ZRC / GO-Ti系的值₃ c ^ ₂涂层是3.047×10 ⁴ Ω·厘米²，这是一个数量级比ZRC涂层的更高。扫描电子显微镜（SEM）和能量色散光谱（EDS）测量表明ZRC / GO-Ti₃ C ₂涂层表现出较低的锌颗粒氧化速度和完整的钢基材。因此，ZRC / GO-Ti ₃ C ₂涂层在四种涂层中均表现出最佳的耐腐蚀性。
