| 摘 要： | 基于静电作用, 阴离子表面活性剂可与阳离子聚铵组装形成复合胶束. 借助阳离子聚铵,复合胶束可以作为模板与硅源协同组装, 形成高度有序的介孔二氧化硅. 本文通过调变不同种类阴离子表面活性剂、合成体系pH值、合成温度及阳离子聚铵和硅源用量等因素, 合成了具有不同介观结构和形貌的介孔二氧化硅. 实验证实阴离子表面活性剂/阳离子聚铵复合胶束模板法是合成介孔二氧化硅的一种通用方法.

| Abstract: | Electrostatic interactions between cationic polyamine and anionic surfactant cause assembly to form composite micelles. The anionic surfactant/cationic polyamine composite micelles can then act as a template to co-assemble with silica precursors to form mesostructured silica. Mesoporous silicas with different mesostructures and morphologies were obtained by changing the synthesis temperature, the amounts of cationic polyelectrolyte or silica precursor and the species of anionic surfactant. This anionic surfactant/cationic polyamine composite micelle template method comprises a general method for synthesizing mesoporous silicas. |
