High flux composite PTMSP-silica nanohybrid membranes for the pervaporation of ethanol/water mixtures
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.
