Abstract
The present disclosure relates to a method of manufacturing a water treatment membrane having high chlorine resistance and high permeability, the method including: forming an aqueous amine solution layer on a porous support, using an aqueous amine solution including a fluorine compound having an epoxy group in a terminal thereof and an amine compound; and forming a polyamide layer containing the fluorine compound by bringing an organic solution containing acyl halide into contact with the aqueous amine solution layer, and a water treatment membrane manufactured using the same.
