pH Sensitive Polysulfone Membranes Prepared by Homogeneous Photo-Initiated Graft Copolymerization

Abstract:

The copolymers of polysulfone-graft-acrylic (PSF-g-PAAc) acid were synthesized by homogeneous photo-initiated graft copolymerization method. Variable affecting the degree of grafting (DG), such as the ultraviolet irradiation time, and the concentrations of the acrylic acid monomer and photoinitiator, were investigated. The graft copolymers were characterized by chemical titration, attenuated total reflection-Fourier transform infrared spectroscopy and x-ray photoelectron spectroscopy analysis. It is verified that acrylic acid groups were present on the polysulfone polymer. Then, membranes were prepared from the PSF-g-PAAc powder with different DG using phase inversion method. It is found that the flux properties of the membranes were dependent on the pH value of the aqueous solution.
