Method for producing self-assembly polymer membrane by non-solvent induced film formation and polymer membrane produced thereby

Abstract

An embodiment relates to a method for producing a self-assembly polymer membrane by non-solvent induced film formation (NIFF), the method including: (a) preparing a polymer solution by mixing an ionized polymer with an organic solvent, (b) preparing a substrate on which a polymer solution coating layer is formed by coating the polymer solution on a substrate and (c) forming an ionized polymer membrane by immersing the substrate on which the polymer solution coating layer is formed in a non-solvent without going through a drying process under elevated temperature conditions. Accordingly, it is possible to produce a nonporous, dense polymer membrane in an efficient way that saves time and energy.
