中文摘要：

聚丙烯及其复合材料的许多性能与其结晶行为和晶体形态有着密切的关系。层状硅酸盐在填充改性聚丙烯的同时，对其结晶形态晶体结构产生很大的影响，最终反映为复合材料性能的差异。本文综述了蒙脱土和高岭土对聚丙烯结晶度、结晶温度、结晶速率和结晶形态等结晶行为的影响。

英文摘要：

There was a strong relationship between the crystallization behavior and crystallization morphology and the properties of the polypropylene and polypropylene based nanocomposites. The crystallization behavior and the crystallization structure were significantly affected by the presence of the layered silicate, resulted in the verification of the properties of the nanocomposites. The effect of the montmorillonite and the kaolin on the crystallinlty, the crystallization temperature, the crystallization rate and the crystallization morphology of polypropylene were discussed.
