ZnS纳米粒子在层状液晶中的原位合成及润滑性能

Lubrication of ZnS nanoparticals synthesized in lamllar liquid crystal

在TritonX-100/C10H21OH/H2O体系层状液晶中原位合成出粒径为20-30nn3ZnS纳米粒子,用高速环-块磨损试验机考察了ZnS纳米粒子在TritonX-100/C10H21OH/H2O体系层状液晶中的润滑性能,并用X射线光电子能谱对其摩擦化学作用机理进行了研究.研究结果表明,ZnS纳米粒子能提高TritonX-100/C10H21OH/H2O体系层状液晶的润滑性能,其在摩擦过程中,发生了摩擦化学反应,在摩擦表面生成了化学反应膜.

The ZnS nanoparticles could be synthesized in lamllar liquid crystal(LLC). The size of ZnS nanoparticles was about 20-30 nm. The friction and wear behaviors of ZnS nanoparticles as an additive in the lamllar liquid crystal. It has been found that the ZnS nanoparticles in lamllar liquid crystal had high loadcarry-ing capacity and good antiwearproperties. The XPS analysis of the worn surfaces indicates that tribochemically reation film was generated during the friction process. This contributes to improve the...
