| 摘 要： | 分别用油酸（OA）、司班-60（Span-60）、十六烷基三甲基溴化铵（CTAB）-二烷基二硫代磷酸吡啶盐（Py-DDP）对MoS2纳米微粒进行表面修饰，考察了修饰后微粒的形貌、在液体石蜡中的分散稳定性和润滑性能，并采用四球摩擦磨损机测试了其摩擦学性能。结果表明，选用不同修饰剂所得到的修饰MoS2纳米微粒的稳定性和摩擦学性能均有不同程度的提高，其中以CTAB—PyDDP修饰MoS2纳米微粒的分散稳定性更佳，摩擦学性能最好。

| Abstract: | The surface-modified MoS_2 nanoparticles were synthesized in a mixture solution of water-ethanol with oleic acid,Span-60 and CTAB-PyDDP as modification agent.The structure of nanoparticles was characterized by transmission electron microscope(TEM),and their dispersion stability,lubricity and tribological properties as additives in liquid paraffin were investigated with four-ball tribometer.Result shows that the dispersion stability and tribological properties of the prepared MoS_2 nanoparticles with different surface-modified reagents are promoted in some extent,and the nanoparticles modified by CTAB-PyDDP have better dispersion stability and tribological properties. |
