Free-standing ZIF-71/PDMS nanocomposite membranes for the recovery of ethanol and 1-butanol from water through pervaporation
Abstract(#br)Free-standing zeolitic imidazolate framework-71 (ZIF-71)/polydimethylsiloxane (PDMS) nanocomposite membranes with 0, 5, 25 and 40\u003cce:hsp sp=\"0.25\"/\u003ewt% ZIF-71 loadings were prepared and the pervaporation separation performance for ethanol and 1-butanol from water was measured. ZIF-71 was stable in water for seven days (both at room temperature and 60\u003cce:hsp sp=\"0.25\"/\u003e°C); the crystal structure and morphology remained the same. ZIF-71/PDMS composite membranes were formed through addition cure and condensation cure methods.
