ONE-STEP PREPARATION PROCESS FOR THIN FILM COMPOSITE MEMBRANE USING DUAL (DOUBLE LAYER)-SLOT COATING TECHNIQUE

WIPO Patent Application WO/2017/116009

A1

The present invention relates to a preparation process for a thin film composite membrane (TFC, hereinafter TFC), and provides a method for preparing 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 coating/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 in an interface of the double layer.
