Synthesis and Characterization of Polysulfone Hydrogels
ABSTRACT

Polysulfone (PSF) membranes are frequently used in ultrafiltration, due totheirchemical and structural stability and mechanical robustness. Despite these advantages, successful utilization of this membrane technology has been greatly limited by the susceptibility of these membranes to fouling, due totheirhydrophobic nature. Here we report on the synthesis and characterisation of hydrophilic PSF membrane materials prepared by incorporation of polyvinyl alcohol, through chemical crosslinking to produce mechanically and chemically stable PSF hydrogels. The hydrogel composition was controlled at three different ratios to evaluate the effect of the PSF contributioni.e.25:75, 50:50 and 75:25. PSF hydrogels were characterized using high resolution scanningelectronmicroscopy (HR-SEM), cyclicvoltammetry (CV), and drop shape analysis techniques. The polysulfone hydrogels formed showed a decrease in contact angle by 50% for all hydrogels regardless of their polysulfone contribution, confirming an improvement in hydrophilic nature. The electron diffusion and ionic transport properties of thehydrogels as immobilised thin films in aqueous solutions,wereevaluated using cyclic voltammetry.
