Abstract Epoxy coatings play an important role in preventing the corrosive medium penetrating into the base metal, but improving its durability in harsh environments is still a challenge. Nanomaterial introduced in epoxy coatings is an effective improvement measure, especially, the use of two-dimensional nanomaterial can effectively block the corrosion medium. In this paper, we use two-dimensional molybdenum disulfide (MoS2) hybrid materials as nanofiller to improve the corrosion resistance of epoxy coatings. MoS2 hybrid materials were obtained by an effective method based on self-oxidation of dopamine and functionalized silane (KH560) grafting. The poly(dopamine) and epoxy groups on the surface of MoS2 enhanced the interaction with EP matrix. The anticorrosive performance of composite epoxy coating with the different content of MoS2 hybrid materials was investigated in detail. An appropriate content (0.8 wt%) in the epoxy coating was obvious to improve its anti-corrosion performance.

具有聚（多巴胺）和环氧基团的二硫化钼作为环氧涂料中的有效防腐增强剂

摘要 环氧涂层在防止腐蚀性介质渗入基体金属方面发挥着重要作用，但提高其在恶劣环境中的耐久性仍是一个挑战。在环氧涂料中引入纳米材料是一种有效的改进措施，尤其是二维纳米材料的使用可以有效阻隔腐蚀介质。在本文中，我们使用二维二硫化钼（MoS2）杂化材料作为纳米填料来提高环氧涂层的耐腐蚀性能。MoS2 杂化材料是通过基于多巴胺自氧化和官能化硅烷 (KH560) 接枝的有效方法获得的。MoS2 表面的聚（多巴胺）和环氧基团增强了与 EP 基质的相互作用。详细研究了不同MoS2杂化材料含量的复合环氧涂层的防腐性能。环氧涂层中适当的含量（0.8wt%）对提高其防腐性能是明显的。
