Title:

PORE-FILLED ION EXCHANGE POLYELECTROLYTE COMPOSITE MEMBRANE FROM WHICH SURFACE ION EXCHANGE POLYELECTROLYTE HAS BEEN REMOVED AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2019/212210

Kind Code:

A1

Abstract:

Disclosed are a pore-filled ion exchange polyelectrolyte composite membrane from which a surface ion exchange polyelectrolyte has been removed and a method for manufacturing same. The ion exchange polyelectrolyte composite membrane exhibits a low membrane resistance and a low in-plane swelling degree, and the membrane thickness is also significantly thinner than that of a commercial membrane, and thus can be used for various applications. In addition, since the ion exchange polyelectrolyte composite membrane is continuously prepared through a roll-to-roll process, the manufacturing process is simple and the manufacturing cost may be significantly reduced.
