Title SEMI-PERMEABLE COMPOSITE MEMBRANE
Abstract Provided is a highly-durable, semi-permeable composite membrane in which that exhibits both high solute removal characteristics and water permeability characteristics. The semi-permeable composite membrane is formed from a porous support membrane and a polymer membrane. The polymer membrane is formed of at least one type of polymer (a) with a positive charge in the repeating unit and at least one type of polymer (b) with a negative charge in the repeating unit and has a crosslinked structure formed by siloxane bonds between polymers with a positive charge (a) and polymers with a positive charge (a), between polymers with a positive charge (a) and polymers with a negative charge (b), and/or between polymers with a negative charge (b) and polymers with a negative charge (b).
