GAS SEPARATION MEMBRANE, MANUFACTURING METHOD FOR THE SAME, AND GAS SEPARATION MEMBRANE MODULE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gas separation membrane having excellent gas permeability, for achieving high gas separation selectivity in which membrane life is prolonged and to provide a manufacturing method for the same and a gas separation membrane module using the same.

SOLUTION: The gas separation membrane includes a support body and a separation layer formed from a resin that is formed on the support body. The separation layer of the gas separation membrane has a hydrophilic modification surface on the side opposite to the support body, and the film thickness of the layer constituting the hydrophilic modification surface is 0.1 μm or less. The surface contact angle of the hydrophilic modification surface using water is 60° or less.
