聚苯乙烯/介孔分子筛复合材料的研究 总被引:1,自引:0,他引:1
采用原位聚合的方法制备了聚苯乙烯/介孔分子筛复合材料。由于介孔分子筛孔径分布狭窄,孔道排列有序,具有很大的比表面积和孔容积,因此在一定条件下单体分子有可能进入分子筛孔道并能在引发剂引发下进行聚合反应。通过IR,TG,XRD,RAM AN,N2吸附,元素分析等对产物进行表征,结果表明,苯乙烯单体进入分子筛孔内并发生了聚合反应。 相似文献

The field of porous, inorganic materials is experiencing explosive growth, as is shown by more than 6000 literature citations since 1994 along with numerous recent symposia and workshops that have been devoted to this topic. Much of the recent interest has been fueled by new synthetic strategies, such as ‘supramolecular templating’, that have enabled precise engineering of pore size, shape, and connectivity on the mesoscopic scale. In general, template-based approaches involving the cooperative organization of organic—inorganic assemblies as intermediates are emerging as a promising conceptual basis for future developments in the field of porous inorganic materials, such as the synthesis of hierarchical morphologies that mimic the intricate structures found so often in nature. 相似文献
