MANUFACTURING METHOD OF FACILITATED TRANSPORT MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a facilitated transport membrane that can easily form a separating function layer inside a tubular porous support.SOLUTION: A manufacturing method of a facilitated transport membrane, which comprises a porous support 3 and a separating function layer 4 and which selectively allows permeation of specific gas, where an inner wall surface of the columnar porous support 3 having a hollow portion is coated with a membrane-producing solution to which a hydrophilic polymer and a carrier that reacts selectively with the specific gas have been added, and after an inner wall surface side of the porous support 3 has been pressurized, the membrane-producing solution loaded on the inner wall surface is dried to form the separating function layer 4 on the inner wall surface of the porous support 3.
