High flux composite PTMSP-silica nanohybrid membranes for the pervaporation of ethanol/water mixtures
(2010) In Journal of Membrane Science 351(1-2). p.160-167- Abstract
- Silica-filled poly(1-trimethylsilyl-1-propyne) (PTMSP) layers were successfully applied for the first time on top of ultrafiltration support membranes and applied in the pervaporative separation of ethanol/water mixtures. Reduction of the thickness of the separating PTMSP top layer and addition of hydrophobic silica particles resulted in a clear flux increase as compared to dense PTMSP membranes. With ethanol/water separation factors up to 12 and fluxes up to 3.5 kg m(-2) h(-1), the prepared supported PTMSP-silica nanohybrid membranes performed significantly better than the best commercially available organophilic pervaporation membranes. Characterization of a polyvinylidene fluoride (PVDF) and a polyacrylonitrile (PAN) support membrane... (More)

Characterization of a polyvinylidene fluoride (PVDF) and a polyacrylonitrile (PAN) support membrane revealed a more open, irregular and hydrophobic surface structure for the former membrane, thus explaining the higher fluxes of the PTMSP/PVDF composite membrane. Because of their promising flux-selectivity combination, the prepared membranes exhibit great potential in the removal of alcohols from aqueous mixtures. (C) 2010 Elsevier B.V. All rights reserved.
