In this work, a melamine functionalized molybdenum disulfide (M-MoS) was prepared and used as fillers to form epoxy (EP)/MoS nanocomposites. The effects of molybdenum disulfide (MoS) and melamine functionalized molybdenum disulfide (M-MoS) loading on the mechanical properties of epoxy composites were investigated and compared. With only addition of 0.8 wt% M-MoS, the tensile strength and modulus of EP/M-MoS nanocomposites showed 4.5 and 4.0 times increase over the neat epoxy. Interestingly, the elongation at break value of EP was also increased with the introduction of M-MoS fillers. These properties could result from the good dispersion and strong interfacial adhesion of M-MoS fillers and the EP matrix. Therefore, this work provides a facile way to produce of high-performance EP nanocomposites.
在本工作中，制备了一种三聚氰胺功能化的二硫化钼（M-MoS）并将其用作填料以形成环氧（EP）/MoS纳米复合材料。研究并比较了二硫化钼（MoS）和三聚氰胺功能化的二硫化钼（M-MoS）的负载量对环氧复合材料力学性能的影响。仅添加0.8 wt%的M-MoS时，EP/M-MoS纳米复合材料的拉伸强度和模量相较于纯环氧树脂分别提高了4.5倍和4.0倍。有趣的是，随着M-MoS填料的引入，EP的断裂伸长率值也有所增加。这些性能可能源于M-MoS填料在EP基体中的良好分散和强界面粘附力。因此，本工作提供了一种制备高性能EP纳米复合材料的简便方法。
