摘要/Abstract

摘要： Novel pH-responsive membranes were prepared by blending pH-responsive amphiphilic copolymers with polyethersulfone (PES) via a nonsolvent-induced phase separation (NIPS) technique. The amphiphilic copolymers bearing Pluronic F127 and poly(methacrylic acid) (PMAA) segments, abbreviated as PMAA_n-F127-PMAA_n, were synthesized by free radical polymerization. The physical and chemical properties of the blend membranes were evaluated by scanning electronmicroscopy (SEM), Fourier transform infrared (FTIR) spectrum, water contact angle, Zeta potential and X-ray photoelectron spectroscopy (XPS). The enrichment of hydrophilic PMAA segments on the membrane surfaces was attributed to surface segregation during the membrane preparation process. The blend membranes had significant pH-responsive properties due to the conformational changes of surface-segregated PMAA segments under different pH values of feed solutions. Fluxes of the blend membranes were larger at lowpH values of feed solutions than that at high pH values. The pH-responsive ability of themembranes was enhanced with the increase of the degree of PMAA near-surface coverage.
