Abstract:
A gas separation composite membrane, containing a gas-permeable supporting layer and a gas separating layer containing a crosslinked polyimide resin over the gas-permeable supporting layer, in which the crosslinked polyimide resin has structure in which a polyimide compound is crosslinked and linked, and the polyimide compound is a copolymer having at least an imide group-containing monomer component and a monomer component having a specific polar group; and a module, a gas separation apparatus and a gas separation method using the same.
