【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為例,在這些非離子表面活性劑與CTAB的復(fù)配體系中制備得到了不同形貌的介孔氧化硅,考察了反應(yīng)體系中各種物質(zhì)濃度的影響;基于研究結(jié)果闡明了介孔氧化硅的形貌調(diào)控機(jī)理。對介孔氧化硅的制備和應(yīng)用具有重要的參考價值。
[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.
