Abstract

PURPOSE: To manufacture highly permeable membrane of uniform pore-diameter easily and constantly, by making a film-shaped material, which is made by casting high molecular liq. dissolved in one or more kinds of solvent, absorb one or more kinds of poor solvent vapor under specific conditions, then by immersing the film in the bad solvent to form a membrane.
