Fluorine-containing polyimide-based composite membrane or asymmetric membrane, their production method and gas separation / concentration method using them |
| abstract |
(57) [Summary] [Objective] The present invention separates a specific component from a mixed gas. It is to provide a composite or asymmetric membrane used for concentration. [Structure] A composite film in which a thin film of an elastomer polymer is formed on a support film made of a 6FDA fluorine-containing aromatic polyimide resin, or an asymmetric film made of a 6FDA fluorine-containing aromatic polyimide resin. |
