聚合物/蒙脱土(MMT)纳米复合材料,特别是剥离型的聚合物/MMT纳米复合材料的制备,是提高聚合物力学性能、耐热性能和阻隔性能的重要途径.然而,对于聚对苯二甲酸乙二醇酯(PET),由于其中等极性,难以得到剥离型的PET/MMT复合材料.本文采用PET缩聚阶段的催化剂醋酸锑对Na-MMT进行插层改性,并用原位聚合法分别制备了PET/Sb-MMT纳米复合材料和PET/Na-MMT纳米复合材料,采用XRD、TEM分析了PET/MMT复合材料的层间距和微观形貌,并通过DSC、TGA、水平燃烧实验和紫外一可见光透过率分析等方法分别考察了PET/MMT复合材料的结晶性能、热稳定性、阻燃性能以及紫外-可见光透光率.研究结果表明:醋酸锑插层MMT有效地提高了MMT的层间距;与PET/Na-MMT相比,PET/Sb-MMT纳米复合材料的层间距略有增加,且MMT片层有剥离趋势;同时,MMT的加人提高了PET的结晶速率,PET/Sb-MMT的热稳定性,阻燃性和透光率与PET/Na-MMT相比均有提高.
