摘　　要：通过添加不同含量的粘土制备了三个不同类型(PP/DK1,PP/PPMA/DK1,PP/PPMA+DK1)纳米粘土/聚丙烯复合材料。通过对实验样品结晶性能的分析,结果表明:与纯聚丙烯结晶图相比,添加适量的粘土作为成核剂,能够使聚丙烯的球晶数量增多,球晶尺寸变小。同时增容剂(PPMA)的加入也会影响PP的结晶,使球晶尺寸不规整。Three kinds of nanocomposites（PP/DK1,PP/PPMA/DK1,PP/PPMA＋DK1） were prepared by the melt intercalation with different grades of organized clay.The crystallization performance of experiment samples were investigated,the results showed that： with the addition of clay-nucleating agent,the grain amount becomes more,the grain size becomes smaller and with the addition of PPMA,the grain size becomes irregular.
