摘　　要：用原位聚合法制备了蒙脱土／环氧树脂(MMT／EP)纳米复合材料.使用X射线衍射(XRD)和透射电镜(TEN)表征了复合材料的结构,并对其力学、热学等性能进行了研究.结果表明,复合材料在有机蒙脱土质量分数为2％时,与纯环氧树脂相比,冲击强度提高了21％,马丁耐热温度和最大热分解速率温度均提高5℃,同时固化线性收缩率也有所降低.Montmorillonite(MMT)/ Epoxy(EP) nanocomposites are prepared via in - situpolymeri-zation. The structure of nanocomposites is characterized by XRD and TEM. The mechan -ical, thermal and other properties are also studied. The results indicate that the impact strength of the composites has increased 21%. Martin heat resistance and the decompositation temperature have respectively raised 5 ℃ than that of epoxy. The shrinkage rate of cure slightly decreases.
