Abstract: The present invention relates to a method for manufacturing a thin film composite membrane for alkaline water electrolysis, and to a thin film composite membrane for alkaline water electrolysis. The present invention can provide a thin film composite membrane, which has excellent water electrolysis performance due to low mass transport resistance and high ion conductivity thereof compared to conventional nonporous membranes and porous membranes, and it is also highly safe by lowering gas permeability and minimizing gas mixing.

Abstract: The present invention relates to a method of manufacturing a high-performance thin film composite (TFC) membrane through a solvent activation process. In the present invention, by using a mixed solvent of a good solvent and a poor solvent as an activating solvent, a conventional polysulfone-based support-based TFC membrane having high water permeance as well as excellent salt rejection may be manufactured.
