Abstract

A hydrophilic membrane that includes a hydrophobic polymer and a water-soluble polymer-metal comlex is provided. This membrane is made by heating a mixture of a hydrophobic polymer, a metal compounds, and a water-soluble polymer. The water-soluble polymer forms complexes with the metal compound and homogeneously entangles with the dissolved hydrophobic polymer to form a viscous dope. The dope is extruded through an annular orifice to form a hollow fiber. The fiber is put in an environment having a controlled humidity so that it becomes partially solidifed, and then, the fiber is put in a coagulation bath. The hollow fiber is formed by phase inversion in the coagulation bath and is collected using a take-up wheel that is partially immersed in a leaching bath.
