Properties of polyethersulfone ultrafiltration membranes modified with polyethylene glycols (original) (raw)

2013, Polymer Engineering & Science

AI-generated Abstract

Polyethersulfone ultrafiltration membranes were developed by incorporating polyethylene glycols (PEGs) with varying molecular weights (400, 1000, and 10,000 g/mol). The study established that the addition of PEG modifies the membrane characteristics, including an increase in hydrophilicity, a reduction in pore size, and a change in flux and water permeability. The performance was optimized with medium molecular weight PEGs, showing improved retention and reduced flux reduction. These findings highlight the potential of PEG modification in enhancing ultrafiltration membrane effectiveness.
