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.
