Abstract:
The present invention relates to a preparation process for a thin film composite (TFC) membrane (hereinafter TFC membrane), and provides a method for the preparation of a membrane through a one-step process using a dual (double layer)-slot coating technique. In the dual (double layer)-slot coating process according to the present invention, a TFC membrane can be prepared by: forming a double-solution layer through a one-step process of performing simultaneous applying/contact of two immiscible solutions, in which two kinds of reactive organic monomers are dissolved, on a porous support; and synthesizing a selective layer through a crosslinking reaction between the organic monomers at an interface of the double layer.

Claim (Index 2):
The method according to  claim 1 , wherein the porous support is polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF), cellulose acetate, polyvinylpyrrolidone (PVP), polysulfone (PSF), polyethersulfone (PES), polyimide (PI), polyetherimide (PEI), polybenzoimidazole (PBI), polypropylene (PP), polyethylene (PE) or polytetrafluoroethylene (PTFE).
