Abstract
In order to enhance the hydrophilicity of PES, A series of sulfonated polyethersulfone (SPES) were readily prepared via a reaction of sulphonation which used chlorosulfonic as sulfonating agent and concentrated sulfuric acid as solvent. Sulfonation was confirmed by Fourier transform infrared spectroscopy and Thermo gravimetric analyzer. We studied forming film characteristic of SPES by phase diagram. The sulfonated PES materials were then utilized as a hydrophilic modifier for fabrication of SPES membranes. The solvent was NMP and PEG-6000 was pore-forming agent. The characteristics of membranes were studied. It was found that the surface hydrophilicity of the modified PES membranes was remarkably enhanced by contact angle. Water flux was obvious increased and antifouling performance was also improved.
