| 摘 要： | 本文综述了制备聚合物 /蒙脱土纳米复合材料的插层方法 ,并对有代表性的结晶性聚合物 /蒙脱土纳米复合材料的结晶性能进行了讨论。蒙脱土的加入对聚合物的结晶有两种作用 ,一方面是对聚合物有异相成核的作用 ,可以提高聚合物的结晶温度和结晶速率 ,降低结晶活化能 ;另一方面是对聚合物结晶生长有阻碍作用 ,导致结晶速率下降 ,结晶活化能提高

| Abstract: | In this paper,the methods of preparing polymer/montmorillonite nanocomposites were briefly reviewed.The crystallization characteristics of some crystalline polymers/montmorillonite nanocomposites were discussed.The addition of montmorillonite played two roles during polymer crystallization process,On the one hand,montmorillonite,which increased crystallization temperature and decreased crystallization activation energy,acted as nucleating agents.On the other hand,the increasing adhesion between polymer and montmorillonite prohibited the crystallization of polymer thus leading to decrease crystallization rate and increase crystallization activation energy. |
