中文摘要：

采用分散聚合法制备了聚甲基丙烯酸缩水甘油酯（PGMA）微球，考察了温度对微球合成的影响；采用聚乙烯亚胺（PEI）对微球进行氨基化改性，通过层层自组装技术制备了微球堆积有机无机复合膜并对其成膜机理进行了研究；初步尝试了通过动态LbL法在陶瓷支撑体上组装微球堆积有机无机复合膜，复合膜显示了一定的醇水渗透汽化分离性能，在复合层数为7层的情况下，复合膜对95%的叔丁醇／水体系的分离因子α为74，通量J为359g／（m^2·h）（75℃）．

英文摘要：

The dispersion polymerization was used to prepare micron-sized uniform poly （glycidylmethacrylate） （PGMA） microspheres. The effect of reaction temperature on the dispersion polymerization of GMA was investigated. PEI was used to modify PGMA microspheres. Then organicinorganic microsphere-based membranes were prepared by layer absorption of amino-PGMA/PAA on the quartz substrates. The film-forming mechanism of coatings was aslo invevstigated. Meanwhile, microsphere-based membranes were prepared on ceremic support membranes. The pervaporation performances of microsphere-based membranes were studied.
