通过共沉淀法制备出PyDDP表面修饰的二硫化钼纳米微粒。采用FT-IR、TEM、元素分析对产物组成和结构进行表征，并考察了其在有机溶剂中的分散性。结果表明：所得表面修饰MoS2纳米微粒尺寸在30 nm~50 nm之间，其在氯仿、丙酮和基础油中具有良好的分散性。利用四球极压抗磨试验考察了其摩擦学性能，磨损试验结果表明表面修饰的MoS2纳米微粒具有良好的抗磨、减摩性能。
Molybdenum disulfide nanoparticles surface-modified by PyDDP was prepared with coprecipitation method used. The composition and structures were characterized by FT-IR,TEM and elemental analysis. The dis-persion was studied in the organic solvent . The results showed that the particle diameter of the prepared MoS2 nano-particles was in a range of 30nm~50nm. The dispersibility in chloroform,acetone and the base oil was good. Their tribologiy behavior was evaluated with a four-ball tester. The tribology results showed that the prepared MoS2 nanop-articles is an oil addition exhibited good friction-reduction and antiwear properties.
