摘要： 在2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为表面活性剂，甲基丙烯酸缩水甘油酯(GMA)和甲基丙烯酸甲酯(MMA)混合物为油相的反相微乳液体系中，合成AgCl纳米粒子，然后通过微乳液聚合制备AgCl/poly(GMA-MMA-AMPS)共聚物有机-无机杂化膜，用于苯/环己烷混合物的渗透汽化分离。利用紫外可见光谱及透射电镜研究微乳液中表面活性剂浓度(CAMPS)、水相中盐浓度(CNaCl、CAgNO3)对AgCl纳米粒子的形成及形貌的影响；通过扫描电镜观察了纳米AgCl粒子在杂化膜中的分布情况。结果表明合成的AgCl粒子近似球状，粒径在20-30nm之间；增加CAMPS和CNaCl、CAgNO3，都导致AgCl粒子粒径减小，粒子数增多；制备的AgCl/poly(GMA-MMA-AMPS)共聚物有机-无机杂化膜中AgCl粒子保持较好的分散性。50wt%苯/环己烷混合物的渗透汽化结果表明，在合适的表面活性剂浓度和水相中盐浓度下，所制备的AgCl/poly(GMA-MMA-AMPS)共聚物有机-无机杂化膜能克服常规高分子膜的trade-off现象，表现出较好的苯/环己烷混合物渗透汽化分离性能。

Abstract: Nanoparticles of AgCl were synthesized in W/O microemulsion using 2-acrylamido-2-methyl propane sulfonic acid (AMPS) as surfactant, glycidyl methacrylate(GMA)/ methacrylate(MMA) mixture as oil phase. And then AgCl/poly(GMA-MMA-AMPS) copolymer organic-inorganic hybrid membranes were prepared by microemulsion polymerization for separation of benzene/cyclohexane mixture by pervaporation. The effect of oncentration of surfactant(CAMPS) and salt (CNaCl 、CAgNO3) on formation and morphology of AgCl nanoparticles were studied by ultraviolet-visible spectrum and transmission electron microscopy(TEM). The results shown that the mean diameters of AgCl nanoparticles are small (10-30nm); the sizes of AgCl nanoparticles increased with ω and concentration of salt (CNaCl、CAgNO3). AgCl nanoparticles maintained well dispersion in AgCl/poly(GMA-MMA-AMPS) copolymer organic-inorganic hybrid membranes. The hybrid membrane demonstrated good separation performance for pervaporation of benzene/cyclohexane mixture, and could overcome the trade-off phenomenon of polymer membranes.
