▎ 摘 要
A novel hydrophilic polysulfone (PSF) membranes integrated with graphene oxide (GO) and bifunctional based poly(methyl methacrylate-co-glycidyl methacrylate) (poly(MMA-co-GMA)) copolymer were prepared. The functional groups of synthesized GO, poly(MMA-co-GMA) and PSF membranes were justified using FTIR spectroscopy. The variety of physicochemical analysis helped to demonstrate the presence GO (1.5 wt%) and poly(MMA-co-GMA) (0-2 wt%) and also its impact on morphology and performance of the membranes. Embedding of the pristine GO, affected the pore forming mechanism due to which the modified membrane exhibited uniform finger-like pores as a result of its hydrophilic filler property. PGC-1 membrane was endowed with maximum pore density, porosity and permeability. There was a significant decline in CA and the amount of BSA adsorbed from 81.2 degrees and 0.22 mg/cm(2) for pristine membrane to 59.7 degrees and 0.06 mg/cm(2), respectively for PGC-2 membrane. By increasing the amount of the copolymer from 0 wt% to 2 wt% the irreversible fouling and total fouling were decreased, which resulted to high flux recovery ratio (F-rr) for the modified PSF membrane. Besides, the o/w emulsion flux obtained for PGC-2 membrane was 6 times greater than that of the unmodified PSF membrane signifying that the foulants were unable to affect the modified membrane. In general, PSF/GO/poly(MMA-co-GMA) membrane with improved fouling resistance and high separation efficiency open up a way for its great potential for protein separation, oil/water emulsion separation and various other similar domains.
