METHOD FOR FABRICATING OF REVERSE OSMOSIS MEMBRANE FROM POLYELECTROLYTE MULTILAYERS AND REVERSE OSMOSIS MEMBRANE OF FABRICATED USING THE SAME

摘要

PURPOSE: A method for manufacturing a reverse osmosis membrane using a polymer electrolyte multilayer thin film is provided to obtain high durability and chemical resistance of the reverse osmosis membrane by using various polymer electrolytes. CONSTITUTION: One surface of a support layer(100) is processed with anions. A support layer processed with anions is immersed in a polymer electrolyte solution(110) with cation. The surface of the support layer is firstly cleaned. The support layer is immersed in the polymer electrolyte with the anion. The surface of the support layer is secondly cleaned. The support layer uses porosity polysulfone ultrafiltration membrane of average diameter of 0.001 to 0.01 um.
