摘要: Provided is a semi-permeable composite membrane which exhibits both high durability and high solute-removal and water-permeation performances. 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 the polymer (a) and the polymer (a), between the polymer (a) and the polymer (b), and/or between the polymer (b) and the polymer (b).
