【摘要】：以聚乙二醇、乙氧基烷基醚、聚氧乙烯-聚氧丙烯-聚氧乙烯三嵌段共聚物为例,在这些非离子表面活性剂与CTAB的复配体系中制备得到了不同形貌的介孔氧化硅,考察了反应体系中各种物质浓度的影响;基于研究结果阐明了介孔氧化硅的形貌调控机理。对介孔氧化硅的制备和应用具有重要的参考价值。
[Abstract]:Taking polyethylene glycol, ethoxyalkyl ether, polyoxyethylene propylene polyoxyethylene triblock copolymer as an example, mesoporous silicon oxide with different morphologies was prepared in the blend system of these Nonionic surfactants and CTAB. The influence of the concentration of various substances in the reaction system was investigated and the morphology regulation mechanism of mesoporous silica was elucidated based on the results. It has important reference value for the preparation and application of mesoporous silica.
