METHOD FOR FACILE PORE CONTROL IN A POLYMER FILM USING AN IONIC LIQUID AND CONTROLLED WATER PRESSURE, AND THE MEMBRANE CONTAINING THE POLYMER FILM MADE BY THE METHOD

摘要

The present invention relates to a producing method of a porous polymer film and a separating membrane using a polymer film produced by the method. The producing method forms pores by tearing a polymer chain weakened by a plasticizing effect due to an ionic liquid, by water pressure.
