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MoS：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。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.
