摘　　要：以正硅酸乙酯(TEOS)、氧氯化锆(Zr OCl2·8H2O)、无水乙醇(Et OH)和水为原料,四乙基溴化铵(TEAB)和N,N-二甲基甲酰胺(DMF)为模板剂,盐酸为催化剂,采用溶胶-凝胶法制备无机复合膜。在锆含量不同的情况下,分别考察两种模板剂对无机膜涂膜液稳定性的影响;并探讨了模板剂对膜性能(即渗透比和渗透通量)的影响。研究表明,两种模板剂均对溶胶的稳定性存在一定程度的作用,且在高锆含量下两者对稳定性的影响更显平稳些;模板剂能够显著提高膜的综合性能。Inorganic composite membrane was prepared by sol-gel method using tetraethyl silicate（TEOS）,zirconium oxychloride octahydrate（Zr OCl2·8H2O）,ethanol absolute（Et OH） and water as raw materials,tetraethylammonium bromide（TEAB） and N,N-dimethyl formamide（DMF） as template,hydrochloric acid（HCl） as catalyst. When the content of the zirconium was different,respectively inspected two templates to the influence of the inorganic coating solution on stability. And discussed the influence of templates on the performance of membrane（i. e. osmosis ratio and permeation flux）. The studies show that two kinds of templates have some effect on the stability of the sol,and under the high zirconium content both impacted on stability more smoothly; and the templates can significantly improve the comprehensive performance of membrane.
