Title:
METHOD FOR MANUFACTURING SELECTIVELY-PERMEABLE MEMBRANE AND WATER TREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2022/024452
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a selectively-permeable membrane, the method including a step for interfacially polymerizing aromatic polyfunctional amine monomers and aromatic polyfunctional acid chloride monomers to form a dense layer on a surface of a water-permeable substrate, wherein the method is characterized in that after being interfacially polymerized, the aromatic polyfunctional amine monomers and the aromatic polyfunctional acid chloride monomers are brought into contact with straight-chain aliphatic polyfunctional amine monomers.
