采用γ-氨丙基三乙氧基硅烷(KH-550)为改性剂，对ZSM-5型沸石粒子进行了改性，以聚二甲基硅氧烷(PDMS )为膜材料，制备了改性沸石填充的PDMS渗透汽化杂化膜.以10％的乙醇/水体系为实验对象，研究了该杂化膜对乙醇的分离性能.结果表明，填充改性沸石粒子能显著提高 PDMS 膜的分离性能.当料液温度为40℃时，分离因子和渗透通量分别达到14．1和348．7 g/(m2?h).

Composite polydimethylsiloxane (PDMS)pervaporation membranes were prepared by incorporating surface modified ZSM-5 particles withγ-Aminopropyltriethoxysilane into the polymer matrix.The separation performances of the hybrid membranes in 10% ethanol-water system were investigated,and results show that adding the modified ZSM-5 particles could improve the separation performances of the membranes remarkably. The separation factor and total flux reached 14.1 and 348.7 g/(m2??h)at 40 ℃,respectively.
