摘　　要：采用反相微乳液聚合法,以甲基丙烯酸甲酯(MMA)和甲基丙烯酸羟乙酯(HEMA)为原料,聚氧乙烯-聚氧丙烯-聚氧乙烯F-127或Tween-80为乳化剂、偶氮二异丁腈(AIBN)为引发剂,银盐AgBF4为烯烃载体的条件下进行共聚合反应,制备了有机-无机复合膜,并用于丙烯/丙烷分离的研究。扫描电镜(SEM)显示AgBF4呈小球状均匀分布在复合膜内,粒径约为60nm;X射线衍射(XRD)测试显示,AgBF4的加入使膜的结晶性能明显下降;气体分离性能测试结果显示,复合膜对丙烯和丙烷的分离因子为5.103,具有明显的促进传递作用。Organic/inorganic hybrid membranes were prepared by reverse microemulsion polymerization using methyl methacrylate （MMA） and hydroxyethyl methacrylate （HEMA） as oil phases, polyoxyethylene-polyoxypropylene-polyoxyethylene F-127 or Tween-80 as emulsifier, azobisisobutyronitrile （AIBN） as initiator and silver tetrafluoroborate （AgBF4） as inorganics. The membranes were used for the separation of propylene and propane based on the facilitated transported interaction of silver ions carriers and olefin. The membrane structure was analyzed by scanning electron microscope （SEM） and X-ray diffraction （XRD）. The results show that AgBF4 particles are evenly distributed in complex membranes with average size of 60 nm. XRD patterns display that the pattern intensity of the membranes decreases significantly with AgBF4 addition. The pure gas permeation experiments show that the separation selectivity of propylene/propane is 5. 103, which has obviously facilitated transport property to propylene.
