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). PS-b-P4VP membranes are first functionalized with a mussel-inspired polydopamine coating and then reacted with amine-terminated pNIPAM. The pH- and thermo-double sensitivities of the modified membranes are proven by determining the water flux under different temperature and pH conditions.
