Abstract To improve the antifooling performance of polyacrylonitrile (PAN) ultrafiltration membrane, acrylic acid (AA) and poly(ethylene glycol) methacrylate (PEG360OHMA) was grafted onto the surface of the membrane by atmospheric dielectric barrier discharge (DBD) plasma induced grafting. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), water contact angle measurements (WCA) and scanning electron microscopy (SEM) were used to characterize the chemical structure of the membranes. The anti-fouling performance of the membranes was evaluated by the bovine serum albumin (BSA) filtration protocol. The results showed that the modified membranes with excellent anti-fouling performance could be fabricated by the atmospheric DBD plasma technique.
