ZIF-71/PDMS Mixed Matrix Membranes for Acetone-Butanol-Ethanol Separations by Pervaporation

Zeolitic imidazole frameworks (ZIF) are known to improve membrane performance in biofuel separation. This research studies ZIF-71/polydimethylsiloxane (PDMS) mixed matrix membrane performance in pervaporation of acetone-butanol-ethanol (ABE) solutions. Membranes with 0, 25, 40, and 60 weight percent (wt%) ZIF-71are synthesized and tested with model solutions of ABE. The results show that 40wt% is the optimal

Fouling performance of ZIF-71/PDMS membrane

The purpose of this research is to work on the free-standing zeolitic imidazolate framework-71 (ZIF-71)/polydimethylsiloxane (PDMS) nanocomposite membranes and provide a technical solution to improve the yield of bio-fermentation to produce biofuels. 40 wt% ZIF-71/PDMS membrane showed an impressive performance on the ideal lab-made solutions with high permeability and selectivity by pervaporation. However, the membrane
