基于zrocl2--nacl的协同作用设计合成乙烷桥键介孔材料
Keywords: 材料科学基础学科,？杂化材料,？介孔材料,乙烷,自组装
Abstract:
？以嵌段共聚物p123(eo20po70eo20)作为模板剂,在无酸介质中利用无机盐zrocl2--nacl的协同作用合成了二维六方结构的乙烷桥联pmos(periodicmesoporousorganosilicas)杂化介孔材料,并借助高分辨透射电镜(hrtem),小角x-射线散射(saxs),等温n2--吸附--脱附以及固体13ccpmasnmr和29sicpmasnmr核磁共振技术等手段对其物性特征进行了表征。结果表明:目标产物具有高度有序的六方孔道排列和有机--无机杂化网络骨架,体现了无机盐组合在目标产物组装过程中的协同作用。
