摘要：利用萘钠插层法剥离制备二硫化钼纳米片层，原子力显微镜（AFM）和透射电子显微镜（TEM）等测试结果表明，其厚度可达几个纳米。同时，利用溶液共混涂膜法制备得到MoS2/PVA（聚乙烯醇）纳米复合材料，并进行了TEM测试，结果显示：MoS2片层很好地分散在PVA基体中。测试结果表明，MoS2/PVA纳米复合材料的热稳定性和玻璃化转变温度都得到提高。加入质量分数1.0%MoS2纳米片层的PVA复合材料的拉伸强度提高了85%，杨氏模量提高了49%。与纯PVA相比，MoS2/PVA纳米复合材料的热性能和机械性能也有明显的提高，原因主要是MoS2纳米片层在PVA基体中分散较好，并且PVA和MoS2之间存在较强的相互作用力。

Abstract: We have prepared MoS2 nanosheets by intercalatation with sodium naphthalenide. Atomic force microscope(AFM) and transmission electron microscopy(TEM) results indicated that the thickness of the nanosheets is several nanometers. MoS2/PVA nanocomposites were also prepared by solvent blending and coating method. TEM analysis indicates that MoS2 nanosheets were well dispersed into the PVA matrix. The thermal stability and glass transition temperature(Tg) of MoS2/PVA nanocomposites were improved.Tensile test showed a 85% increase in tensile strength and a 49% improvement in Young′s modulus upon incorporation of only 1.0% of MoS2 nanosheets. The improvements in the thermal and mechanical properties of MoS2/PVA nanocomposites were attributed to the good dispersion of MoS2 nanosheets and strong interactions between PVA and MoS2.
