Surface modification of poly(ether sulfone) ultrafiltration membranes by low-temperature plasma-induced graft polymerization

摘要

Commercial poly(ether sulfone) (PES) membranes were modified using low-temperature helium plasma treatment followed by grafting of N-vinyl-2-pyrrolidone (NVP) onto PES ultrafiltration (UF) membranes. The NVP-grafted PES surfaces were characterized by Fourier transform infrared attenuated total reflection spectroscopy and electron spectroscopy for chemical analysis. In general, the results provide a foundation for using low-temperature plasma-induced grafting on PES with a variety of other molecules.
