Poly(phenylene oxide) (PPO) membranes with sulfonic groups were prepared by two methods: plasma-initiated surface grafting of sodium styrenesulfonate or chemical sulfonation (with chlorosulfonic acid) of PPO, followed by membrane preparation from the modified material. The presence of ionic groups g

Some properties of ultrafiltration polysulfone membranes modified with n-BuNH2 and n-BuNH2/Ar plasmas were studied. Contact angle measurements, XPS and SEM were used to characterize the surface changes. Pore size estimation, water transport and filtration parameters helped to describe changes in fil
