Corrosion is a natural process between a metal and its environment that can gradually cause catastrophic damage to the metal equipment, which would have economic implications. Consequently, several protective methods have been utilized to prevent metals from severe degradation. Organic polymeric coatings have been widely used as the most convenient and cost-effective method to boost metals' anti-corrosion properties. Nonetheless, these coatings have a significant amount of solvent, resulting in shrinkage and micro defects in the films during the curing process. Many studies have verified that transition metal carbides/nitrides (MXenes) can form a "labyrinth effect" in the polymeric coatings due to their "nano-barrier effect". Furthermore, based on their sheet-like structures, they can considerably cover the surface defects of the polymeric films. Therefore, the penetration of corrosive elements can be substantially curbed. It is the first review that specifically focused on the new family of 2D nanomaterials, i.e., MXenes, and discussed their applications in corrosion protection systems. The MXenes' pros and cons in the polymeric matrixes as nanofillers will be clarified. Moreover, the synthesis and functionalization methods of the MXenes, their applications, and corrosion protection mechanism will be explored. Subsequently, the MXenes' superiority over other 2D nanomaterials will be highlighted while their future perspectives and industrial applications will be predicted.
腐蚀是金属与其环境之间的自然过程，会逐渐对金属设备造成灾难性损害，这会产生经济影响。因此，人们采用了多种防护方法来防止金属严重降解。有机聚合物涂层作为提高金属防腐性能的最便捷且经济高效的方法，已被广泛使用。然而，这些涂层含有大量溶剂，在固化过程中会导致薄膜收缩和出现微缺陷。许多研究证实，过渡金属碳化物/氮化物（MXenes）由于其“纳米阻隔效应”，可在聚合物涂层中形成“迷宫效应”。此外，基于其片状结构，它们能大量覆盖聚合物薄膜的表面缺陷。因此，可大幅抑制腐蚀性元素的渗透。这是第一篇专门聚焦于二维纳米材料新家族即MXenes，并讨论其在腐蚀防护系统中应用的综述。将阐明MXenes作为纳米填料在聚合物基体中的优缺点。此外，还将探索MXenes的合成与功能化方法、其应用及腐蚀防护机制。随后，将突出MXenes相对于其他二维纳米材料的优势，同时预测其未来前景和工业应用。
