초록

Polyethersulfone, polysulfone, polyacrylonitrile and cellulose acetate were recently developed to make a membrane for medical application. The membrane made of hydrophobic polymer showed good mechanical properties, however, it caused hydrophobic interaction which results in a disadvantage of short replacement cycle due to the biofouling on the membrane surface. On the other hand, the membrane made of a hydrophilic polymer showed a high swelling ratio, which absorbs a large amount of water and eventually results in a low mechanical strength. In this study, anti-fouling ultrafiltration membranes were prepared using syndiotactic poly(vinyl alcohol) (PVA) via a phase inversion technique and a surface saponification. The biofouling and the permeability of membranes were investigated by controlling the tacticity of PVA.
