摘要：过去数十年中，介孔材料SBA－15已经成为广大科研工作者的研究热点．传统介孔材料SBA－15通常含有6～8nm的有序介孔孔道，但这无法满足诸如蛋白质等生物大分子药物的装载需求。本文通过一种新颖的溶剂热后处理法得到了介孔材料SBA－15，并通过相关手段对其进行表征．结果表明，所得材料具有明显的孔径扩大效果，其介孔孔道可达到10nm以上，且具有良好的有序性．与此同时，所得材料中含有的有机模板剂P123（EO20PO70EO20）得到了有效地脱除，从而避免了传统SBA－15合成过程通常采用的高温煅烧或有机溶剂萃取等步骤．此外，所得材料在达到一定骨架缩聚度的同时，还保留了大量硅羟基基团，这为材料表面的进一步修饰处理提供了可能．该方法在其他类型介孔硅材料的扩孔方面也有着良好的应用价值．
The synthesis of mesoporous material SBA-15 has been extensively reported in the past decades, which possesses a pore diameter of 6-8 nm on average. Here, a simple post-synthesis procedure has been developed to synthesize SBA-15 with further expanded pore diameter to above 10 nm simply by a solvothermal treatment replacing traditional hydrothermal step for mesopore template removal, which results in efficient pore expansion and the significantly promoted condensation of silica framework as well. This facile approach is believed applicable for pore expansions of other kinds of mesoporous silica materials.
