| 摘要: 在大分子F127为表面活性剂的反相微乳液体系中，合成AgCl纳米粒子。然后通过聚合制备AgCl/F127-PMMA有机/无机杂化膜，用于苯/环己烷混合物的渗透汽化分离。利用电导率仪、紫外可见光谱及透射电镜研究微乳液的增溶水量(ω)对微乳液结构、胶束中AgCl粒子的生成和形貌的影响。结果表明：合成的AgCl粒子粒径小于10 nm；增加微乳液的ω，生成的AgCl粒子变大。聚合后制备的AgCl/F127-PMMA有机/无机杂化膜中，AgCl粒子能保持较好的分散性。50wt%苯/环己烷混合物的渗透汽化结果表明，在合适的ω下，所制备的AgCl/F127-PMMA有机/无机杂化膜能克服常规高分子膜的trade-off现象，表现出较好的分离性能。 |

| Abstract: Nanoparticles of AgCl were synthesized in water-in-oil microemulsion using poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) block copolymers(F127) as a surfactant. And then AgCl/F127-PMMA organic/inorganic hybrid membranes were prepared for separation of benzene/cyclohexane mixtures by pervaporation. The effect of on the structure of microemulsion and morphology of AgCl nanoparticles were studied by conductivity meter, ultraviolet-visible spectrum and transmission electron microscopy(TEM). The results shown that the mean diameters of AgCl nanoparticles are small (1~10 nm). The sizes of AgCl nanoparticles increased with ω. AgCl nanoparticles maintained well dispersion in AgCl/F127-PMMA organic/inorganic hybrid membranes. The results of pervaporation indicated that the hybrid membrane has well separation performance, which could overcome the trade-off phenomenon of polymer membranes. |
