Preparation and characterization of ECTFE solvent resistant membranes and their application in pervaporation of toluene/water mixtures

► ECTFE asymmetric dense membranes by TIPS casting. ► NMP as solvent and four plasticizer additives. ► Membranes resistant to most aggressive organic solvents. ► Membranes tested for VOC (toluene) removal from water by pervaporation. ► Effect of downstream pressure on flux and selectivity.
