【Abstract】 Molybdenum disulfide (MoS 2) 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 MoS 2 nanoparticles was investigated. The morphology and structure of these prepared particles were characterized by means of TEM and IR, etc.. The results showed that MoS 2 nanoparticles modified by cetyl trimethyl ammonium chloride were uniform, their diameter were around 100 nm, and showed some lipophilic characteristics.更多还原
