An isoporous integral asymmetric block copolymer membrane obtained by a non‐solvent solvent exchange process is reported by Volker Abetz and co‐workers on page 731. The surface pores can be reversibly closed and opened by changing the pH value. Postmodification of this membrane with a temperature‐sensitive block leads to a double stimuli‐responsive membrane, in which the pores can be reversibly opened...
Double stimuli‐responsive membranes are prepared by modification of pH‐sensitive integral asymmetric polystyrene‐b‐poly(4‐vinylpyridine) (PS‐b‐P4VP) diblock copolymer membranes with temperature‐responsive poly(N‐isopropylacrylamide) (pNIPAM) by a surface linking reaction. PS‐b‐P4VP membranes are first functionalized with a mild mussel‐inspired polydopamine coating and then reacted via Michael addition...
