Antifouling performance of poly(acrylonitrile)-based membranes: From green synthesis to application

▶ PAN:PAN-g-PEO membranes exhibit distinct morphologies depending on the composition ratio of the graft polymer. ▶ PAN:PAN-g-PEO (70:30) present better morphological (larger pores) and mechanical (less stiff) properties for biomacromolecules filtration processes. ▶ Different non-fouling capacities and different permeation profiles for BSA and starch were achieved according to the pH of the feed solutions.
