Title:
REVERSE OSMOSIS COMPOSITE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/250116
Kind Code:
A1
Abstract:
The present invention addresses the problem of achieving a novel reverse osmosis membrane (more specifically, reverse osmosis composite membrane) that is capable of suppressing biofouling. The problem is solved by using a reverse osmosis composite membrane which is obtained by chemically modifying a surface thereof with a compound that has an amino group, that is obtained by modifying the amino group with two molecules of an α-picolyl group, and that has a dipicolylamine structure.
