Abstract
Zwitterionic (ZI) membranes are well-known for their high resistance to protein fouling during ultrafiltration (UF). In this work, zwitterionic chitosan (ZICS) was firstly obtained by a Schiff-base formation and a sulfonation reaction. Then a series of zwitterionic organic–inorganic hybrid ultrafiltration membranes were prepared through linking ZICS with poly vinyl alcohol (PVA) using tetraethyl orthosilicate as a bridge, where the density of...
