摘要：

In this study, pH-sensitive polyethersulfone (PES) hollow fiber membrane was prepared by blending a copolymer of poly (styrene-alt-maleic anhydride) (PSMA). The PSMA alternating copolymer was synthesized by a traditional synthetic route, and was characterized by Fourier transform infrared spectroscopy (FOR) analysis, nuclear magnetic resonance (H-1 NMR) and gel permeation chromatography technique (GPC). The PES/PSMA membrane was then transformed to carboxylic PES/PSMA-H carboxylic membrane using sodium hydroxide solution, by which the anhydride groups were transformed to carboxyl groups, and the modified membranes showed excellent pH-sensitivity and pH-reversibility. Furthermore, the alternating copolymer modified PES hollow fiber membranes showed evident hysteresis of water flux, for which it would take several hours to reach the equilibrium state.
