摘　　要：分别采用十六烷基三甲基溴化铵(CTAB)以及偶联剂γ-氨丙基三乙氧基硅烷(KH550)对锂皂石进行修饰,制备有机化的锂皂石(Laponite)。然后将有机化的锂皂石与聚丙烯(PP)进行熔融共混,制备PP/有机化锂皂石复合材料。红外光谱(FT-IR)和热失重分析表明改性剂成功的修饰了锂皂石。PP/有机化锂皂石复合材料的断裂伸长率较PP有明显的改善。organo-lapontie and polypropylene（PP）/ laponite composite were prepared successfully. Infrared spectra （FT-IR） and thermogravimetric （TG）analysis showed that the laponite was modified successfully. Also, the mechanical properties of the composite were determined. The results showed that for CTAB modified Laponite,elongation at break of the PP/hectorite increased markedly and reached peak value when the concentration of the hectorite was 1-5 wt %.
