摘　　要：综述了聚丙烯(PP)／蒙脱土(MMt)纳米复合材料的制备,蒙脱土有机化处理,插层方法以及PP／MMt纳米复 合材料的力学性能、结晶性能等研究进展。有机改性剂可促使蒙脱土片层间距增大,有利于聚丙烯长链插入其间;极性相 容剂增加了MMt与PP基体相容性及MMt在PP基质中的分散性,提高界面粘结和力学性能。纳米蒙脱土具有异相成核 作用,但结晶速度受蒙脱土片层间距及PP基质等多种因素影响。This paper reviewed the preparation of PP/MMt nanometer compound material, organic treatment of MMt,intercalation method, as well as progress in research of mechanical properties and crystallizing properties of PP/MMt nanometer compound material. Organic modifying agent can expand MMt lamellas;polarity compatilizer increases the compatibility of MMt and PP matrix and the dispersibility of MMt in PP matrix, and promotes the caking and mechanical properties of interfaces. Nanometer MMt has the feature of heterogeneous nucleation, but the crystallizing speed is affected by various factors such as intervals of MMt lamellas and PP matrix.
