摘　　要：采用沉淀法制备 Mo S2 纳米颗粒 ,考察了不同类型的表面活性剂对生成 Mo S2 颗粒的影响。用透射电子显微镜 ( TEM)考察了几种表面活性剂对颗粒形貌的影响 ;用红外光谱 ( IR)考察了改性后的纳米颗粒的表面结构。结果表明 ,阳离子型表面活性剂对 Mo S2 纳米颗粒的改性效果最好 ,十六烷基三甲基氯化铵改性的 Mo S2 纳米颗粒的粒径在 1 0 0 nm左右 。Molybdenum disulfide (MoS2) nanoparticles were prepared by precipitation method at the presence of different surfactants, such as dialkyldithiophosphate (DDP), cetyl trimethyl ammonium chloride and polyvinyl alcohol (PVA). The influence of surfactants on the size and appearance of prepared MoS2 nanoparticles was investigated. The morphology and structure of these prepared particles were characterized by means of TEM and IR, etc. The results showed that MoS2 nanoparticles modified by cetyl trimethyl ammonium chloride were uniform, their diameter were around 100 nm, and some lipophilic characteristics were shown.
