摘　　要：采用锂离子插层法对二硫化钼(MoS_2)进行剥离,用巯基乙胺对其片层表面进行氨基修饰得到氨基化二硫化钼(MoS_2-NH_2),然后与ε-己内酰胺单体发生原位开环聚合反应获得聚酰胺(PA)接枝的二硫化钼(PA-g-MoS_2),用FT-IR、XRD、XPS对PA-g-MoS_2的结构进行表征,结果表明,聚酰胺成功接枝到二硫化钼表面.再将PA-g-MoS_2与聚酰胺通过熔融共混法制备出功能化二硫化钼/聚酰胺(MPA)复合材料,用TGA、DSC和DMA研究MPA复合材料的热学性能和力学性能.结果表明,随着PA-g-MoS_2在复合材料中含量的增加,复合材料的热学性能提高,力学性能略有下降.Molybdenum disulfide （MoS2） was exfoliated by Li~ intercalation method. The exfoliated MoSe was functionalized with cysteamine to obtain MoS2-NHe. The PA-g-MoS2 was synthesized via ring-opening polymerization using ε-caproiactam initiated by MoSz-NH2 and characterized by FT-IR, XRD and XPS. The functionalized MoS2/polyamide composites （MPA） were fabricated via a simple melt compounding method. The thermal and mechanical properties of MPA were characterized by DSC, TGA and DMTA, which indicated that the thermal stability of PA was improved apparently with the increase of PA-g-MoS2, while the mechanical property was decreased.
