Development and Evaluation of Filtration Performance of ZnO-Doped PEI Composite Membranes
Polyetherimide (PEI)-based membranes were fabricated by phase inversion to examine the effects of zinc oxide (ZnO) nanoparticles and polyvinylpyrrolidone (PVP) on membrane structure, wettability, permeation, and fouling behavior. Six formulations comprising neat PEI, PEI/PVP, two ZnO loadings (0.5 and 1 wt.%), and the...
