Abstract：

Membrane fouling is one of the most important challenges faced in ultrafiltration (UF) operations . In this study , a three layers composite ultrafiltration membrane contains titanium dioxide(TiO2) was prepared by electrostatic spinning technology . Hydrophilic nano TiO2 was added in PVA by doping technology . Finally through the mixed solvent for processing , the high flux , high rejection ratio composite electrospinning ultrafiltration membrane with good antifouling property was made .
