A novel method to fabricate high permeance, high selectivity thin-film composite membranes
Abstract(#br)We report a thin-film composite (TFC) membrane fabrication method based on transfer of a pre-formed, cured active layer onto a microporous support. The active layer is cast on a polyvinyl alcohol (PVA) water-soluble film and cured, then the active side of the bilayer is placed against the skin side of the microporous support and the water soluble layer is dissolved. This method can be used with supports of relatively high pore size and porosity, thus reducing mass transfer resistance from the support.
