摘要：为了得到良好亲油性的二硫化钼（MoS₂）粉体，采用湿法改性工 艺，分别以硅烷偶联剂（KH570）、硬脂酸（SA）及其复合改性剂对 MoS₂粉体进行表面改性，并进行粉体悬浮液的浊度、活化指数等分析。 结果 表明：改性 MoS2 粉体疏水亲油性提高；对改性前后的 MoS₂ 粉体进行了 FT-IR 及 XRD 的结构表征，结果表明，粉体粒子表面成功地被有机物 包覆；将改性 MoS₂ 粉体填充于聚苯硫醚（PPS）、聚丙烯（PP）复合材料， 力学拉伸试样断口的 SEM 分析表明： 改性 MoS₂ 在 PPS-PP 复合材料 中无团聚且分散均匀。

Abstract：In order to obtain the molybdenum sulfide （MoS₂） powder with good lipo philicity， MoS₂ powder was modified with KH570， SA and their compounds. The synthesis result of turbidity and activation data showed that the lipophilicity of modified MoS₂ increased. The FT-IR and XRD results showed that the structure of modified MoS₂ were not changed and its parti cles’surface were covered with organic modifiers. The SEM images-indicat ed that the modified MoS2 dispersed into polyphenylene sulfide-polypropg lene（PPS-PP） composites evenly and without agglomeration.
