【摘要】 <正> 自1987年日本[1]报道用原位插层聚合的方法制备尼龙6/粘土纳米复合材料以来,聚合物/粘土纳米复合材料引起了广泛的关注,它与常规聚合物基复合材料相比具有更高的强度、刚度、韧性、优良的热稳定性及尺寸稳定性。迄今为止,有关聚有机硅倍半氧烷(PSQ)/粘土纳米复合材料的研究十分有限。本研究用一种含硅氧烷链聚合物表面活性剂处理钠基蒙脱土(Na-MMT)得到有机化修饰的蒙脱土(OMMT),然后用原位插层聚合方法口[3]制备得到剥离型聚甲基硅倍半氧烷(PMSQ)/粘土纳米复合材料。更多还原

【Abstract】 In recent years, the synthesis of polymer/layer silicate nanocomposites has received considerable attention. The promising composite materials exhibit remarkable improvements of material properties when compared with the matrix polymers alone. Improvements can include a high storage modulus, increased tensile and flexural properties, a decrease in gas permeability and flammability, and so forth.Polymethylsilsesquioxane(PMSQ)-montmorillonite nanocomposites were prepared by in situ intercalative polymerization. The dispersion of the MMT layers was characterized by X-ray diffraction.更多还原
