In recent years, polymer nanocomposites based on 2D materials have aroused widespread research interest. MoS₂ exhibits many excellent properties due to its unique structure, such as mechanical properties, thermal stability, and fire resistance properties. It has great potential as a polymer reinforcement material and functional nanofiller. However, it is well known that the exfoliated MoS₂ layers have a tendency to aggregate during mixing with polymers, which results in the polymer performance cannot be effectively improved. In this work, clay was introduced into molybdenum disulfide (MoS₂) to improve the dispersion of exfoliated MoS₂. After co-deposition, two different layered fillers co-stacked to form a novel clay/MoS₂ composite. The presence of clay in the MoS₂ slurry prevented aggregation of the individual clay and MoS₂ layers. The resulting clay/MoS₂ composite was further used as fillers to form epoxy/clay/MoS₂ nanocomposites. The effects of clay, MoS₂ and clay/MoS₂ mixture on the properties of epoxy nanocomposites were investigated and compared. It was found that combining clay and MoS₂ allows the enhancement of tensile strength and tensile modulus. Additionally, due to the well co-dispersion of clay and MoS₂, the thermal stability and mechanical properties of epoxy/clay/MoS₂ nanocomposites are higher than those of epoxy/clay and epoxy/MoS₂ nanocomposites. Therefore, this work provides a facile way to produce high-performance epoxy nanocomposites.

近年来，基于二维材料的聚合物纳米复合材料引起了广泛的研究兴趣。MoS ₂由于其独特的结构而表现出许多优异的性能，例如机械性能、热稳定性和耐火性能。它作为聚合物增强材料和功能性纳米填料具有巨大的潜力。然而，众所周知，剥离的MoS ₂层在与聚合物混合时有聚集的趋势，导致聚合物性能无法得到有效改善。在这项工作中，粘土被引入二硫化钼 (MoS ₂ ) 以改善剥离的 MoS ₂的分散。共沉积后，两种不同的层状填料共同堆叠形成新型粘土/MoS₂复合。MoS ₂浆料中粘土的存在防止了单独的粘土和MoS ₂层的聚集。所得粘土/MoS ₂复合材料进一步用作填料以形成环氧树脂/粘土/MoS ₂纳米复合材料。研究并比较了粘土、MoS ₂和粘土/MoS ₂混合物对环氧纳米复合材料性能的影响。发现结合粘土和MoS ₂可以提高拉伸强度和拉伸模量。此外，由于粘土和 MoS ₂良好的共分散性，环氧树脂/粘土/MoS ₂的热稳定性和机械性能纳米复合材料高于环氧树脂/粘土和环氧树脂/MoS ₂纳米复合材料。因此，这项工作为生产高性能环氧纳米复合材料提供了一种简便的方法。
