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 through a specific crosslinking chain, the specific crosslinking chain has at least one kind of linking group selected from the group consisting of —NRaC(═O)—, —NRbC(═O)O—, —CH2OCH2—, —CH2SCH2—, —OC(═O)O—, —C(═O)O−N+(Rc)3—, —SO3−N+(Rd)3— and —PO3−N+(Re)3—, and Ra, Rb, Rc, Rd and Re each independently represent a hydrogen atom or a substituent.
