Integral asymmetric membranes from PS-b-P2VP-b-PEO triblock terpolymers by phase inversion are shown for the first time. The membranes are compared with their PS-b-P2VP-precursors in terms of morphology, water flux, retention capacity, and contact angle. The presence of the short PEO block leads to a higher water flux and smaller contact angle due to its hydrophilicity. The hydroxyl end group may be useful for post-functionalization after membrane formation.
