| 摘 要： | 用一种新型的有机试剂制备有机蒙脱土，并将有机蒙脱土与环氧树脂复合制备了环氧树脂／蒙脱土纳米复合材料。研究结果表明，这种新型的有机改性剂是一种高效的插层剂。同时表现出对环氧树脂固化明显的促进作用。由于有机蒙脱土层间催化中心的引入，将有机蒙脱土与环氧树脂复合可成功制备纳米复合材料。当有机土含量小于8份(相对于100份环氧树脂)时有机土以剥离的纳米级片层结构为主，当有机土含量大于8份时有机土以剥离和插层的纳米结构并存。带活性基团的有机土使环氧树脂的凝胶活化能降低，使复合材料的耐热性能得到较大的提高。

| Abstract: | In this article,a new organic modifier was adopted to prepare organo-montmorillonite(OMMT).The results show that the montmorillonite could be highly intercalated by the modifier and the resulted organo-montmorillonite shows obvious catalytic nature towards the curing of the epoxy resin.The epoxy resin/montmorillonite nanocomposite is successfully prepared as the presence of catalytic center between the galleries of the montmorillonite.And the nanocomposite shows improved thermal stability. |
