中文摘要	capillary supported ultrathin homogeneous silicalite-poly(dimethylsiloxane) nanocomposite membrane for bio-butanol recovery
英文摘要	an ultrathin (300 nm) homogeneous silicalite-poly(dimethylsiloxane) (pdms) nanocomposite membrane was fabricated on capillary support by a "packing-filling" method. firstly, silicalite-1 nano-crystals were deposited onto a porous alumina capillary support using dip-coating technique (packing); secondly, the interspaces among the nano-crystals were filled with pdms phase (filling). no voids between nano-crystals and pdms phase were observed by scanning electron microscopy (sem), suggesting good zeolite-polymer adhesion. the membrane possesses very high flux (5.0-11.2 kg m(-2) h(-1)) and good separation factor (25.0-41.6) for the pervaporative recovery of iso-butanol from aqueous solution (0.2-3 wt.%) at 80 degrees c. such properties offer great potential towards applications in fermentation-pervaporation coupled processes. the effects of feed temperature and concentration on the pervaporation performance of this nanocomposite membrane were investigated.
