Abstract

An asymmetric p(VDF–HFP) pervaporation membrane with an ultra-thin dense skin layer was fabricated through the controlled solvent evaporation method and the two step-coagulation bath-phase-inversion method. The membrane was used to concentrate ethanol from an aqueous solution. The total flux reached 2.4 kg m−2 h−1. Ethanol was concentrated from 5.1 wt% to 24.0 wt%.
