氯化银/聚甲基丙烯酸甲酯有机-无机杂化膜的研究

STUDY OF AGCL/PMMA ORGANIC-INORGANIC HYBRID MEMBRANE

以甲基丙烯酸甲酯(MMA)为油相,利用微乳液聚合技术制备了氯化银/聚甲基丙烯酸甲酯(PMMA)有机-无机杂化膜。扫描电镜分析了膜的结构,结果表明微乳液聚合后形成了以氯化银为核,聚甲基丙烯酸甲酯为壳的核-壳型无机-有机杂化膜材料;氯化银微粒在聚甲基丙烯酸甲酯中均匀分散,形状规则,粒径大小均在2μm以下。环己烷、环己烯在氯化银/聚甲基丙烯酸甲酯无机-有机杂化膜中的溶胀吸附性能研究结果表明,与聚甲基丙烯酸甲酯膜相比,环己烯在杂化膜中的溶胀吸附性能显著提高,而环己烷的溶胀吸附性能却相差不大。

AgCl//PMMA organic-inorganic hybrid membrane was prepared by reverse microemulsion polymerization using methyl methacrylate （MMA） as oil phase.The membrane structure was analyzed by scanning electron microscope （SEM）,and it was showed that core-shell organic-inorganic hybrid materials were formed with AgC1 as the core and PMMA as the shell, AgC1 particulates under 2~ m were uniformly dispersed in the PMMA. The swelling-sorption behavior of the cyclohexane and cyclohexene in AgC1/PMMA hybrid membrane was measured ,and the result indicates that the sorption capacity of cyclohexene in the hybrid membrane was enlarged in comparison with pure PMMA membrane, but the sorption behavior of cyclohexane was less changed.
