A facile method for synthesis of pegylated polyethersulfone and its application in fabrication of antifouling ultrafiltration membrane

Abstract

Pegylated polyethersulfone (PES) was readily synthesized via a reaction of chlorosulfonated PES with oligomeric poly(ethylene glycol) (PEG). The pegylated PES materials were then utilized as a hydrophilic modifier for fabrication of PES ultrafiltration membranes. It was found that the surface hydrophilicity of the modified PES ultrafiltration membranes was remarkably enhanced with an increase of pegylated PES content. Liquid porosimetry and …
