摘要
Ultrafiltration polysulfone membranes were modified with plasma of CO2. As a result highly hydrophilic surfaces of acidic character were obtained. SEM studies and pore size determination revealed that prolonged treatment caused severe surface degradation, increase of pore size and widening of their distribution. Water flux changes with treatment time, showing minimum Value for 2 min. Excellent protein transport parameters of modified membranes were obtained, especially in basic solution.
