Abstract

To minimize energy consumption and carbon footprints, pervaporation membranes are fast becoming the preferred technology for alcohol recovery. However this approach is only confined to small-scale operations as the flux of standard rubbery polymer membranes remain insufficient to process large solvent volumes, while membrane separation using glassy polymer membranes are prone to physical aging. This study reports the alcohol affinity and intrinsic porosity of networked, organic, microporous polymers can simultaneously overcome physical aging, drastically enhance both flux and selectivity of a super glassy polymer, poly-[1-(trimethylsiyl)-propyne] (PTMSP). Slight loss in alcohol transportation channels in PTMSP is compensated by the alcohol affinity of the microporous polymers. Even after continuous exposure to aqueous solutions of alcohols, PTMSP pervaporation membranes loaded with the microporous polymers outperform to state-of-the-art and commercial pervaporation membranes.
