Abstract
⸠A new polyimide 6FDA-NDA/DABA has been synthesized for ethanol dehydration. ⸠Thermal, diamino and diol cross-linking modifications are employed. ⸠The effects of cross-linking on membrane morphology and performance are studied. ⸠The cross-linked membranes show high fluxes and comparable separation factors. ⸠The mechanical strength of the membranes is reasonable for practical applications.
