Thin-film zeolite-filled silicone/PVDF composite membranes were fabricated by incorporating zeolite particles into PDMS (poly(dimethylsiloxane)) membranes. The morphology of zeolite particles and zeolite filled silicone composite membranes were characterized by SEM. The zeolite-filled PDMS/PVDF composite membranes were applied for the pervaporation of ethanol/water mixtures and showed higher flux compared with that reported in literatures. The effect of zeolite loading and Si/Al ratio of zeolite particles on pervaporation performance of ethanol/water mixtures was investigated. With the increase of zeolite loading from 10% to 30%, the total flux increased significantly from 265.0 g/(m~2h) to 820.7 g/(m~2h) with 5 wt% ethanol feed concentration at 50℃, and the separation factor increased from 11.3 to 13.7. The effects of operation temperature and ethanol feed concentration on pervaporation performance were also studied. As the temperature increased from 40℃ to 80℃, the separation factor varied from 12.1 to 13.7 which maintained the maximum value at 50℃, and the total flux increased exponentially from 435.5 g/(m~2h) to 2993.8 g/(m~2h) with 30% zeolite loading. Besides, the zeolite filled PDMS/PVDF composite membrane with 30% zeolite loading was ethanol perm-selective over a wide range of ethanol feed concentration (5 wt%-90 wt%), and especially showed excellent pervaporation performance in the low concentration range.
