利用有机大分子ＣＴＡＢ的自组装体为模板来调制正硅酸乙酯（ＴＥＯＳ）的水解缩聚，于气－液界面上制备出非担载的ＳｉＯ２无机膜．对取膜时间进行了选择，考察了仿生制备ＳｉＯ２膜过程中物料配比对成膜质量的影响，对其进行了优化。由ＣＴＡＢ极性头基排列而成的六边形区域聚集于溶液表面，ＴＥＯＳ在其内部的水解缩聚及随后的层层复制过程形成了仿生合成膜的空间网络结构．
The self-assembly of organic macromolecule CTAB was used as a template to prepare the hydrolytic polycondensation of tetraethoxysilane (TEOS), and a non-supported SiO2 inorganic membrane was prepared on the gas-liquid interface. The filming time was selected, and the effect of material ratio on the film quality during biomimetic SiO2 film preparation was investigated and optimized. The hexagonal region arranged by the CTAB polar head group is concentrated on the surface of the solution. TEOS hydrolyzed and polycondensated in the interior and the subsequent layer-by-layer replication formed the spatial network structure of the biomimetic synthetic membrane.
