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 14):
The method according to  claim 13 , wherein each of the first solution and the second solution has a flow rate per unit width of 0.016\u00d710 \u22126  to 416.6\u00d710 \u22126  m 2 /s.
