| titleOfInvention | Porous membrane, gas separation membrane and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide high separation performance when used as a porous support layer of a gas separation membrane by suitably controlling the porous structure near and inside the surface of a polyimide porous membrane. Further, the present invention provides a porous membrane excellent in mechanical strength and the like, a gas separation membrane using the same as a porous support layer, and a method for producing the same. SOLUTION: A step of preparing a film-forming stock solution uniformly dissolved in a mixed solvent of an organic solvent for uniformly dissolving a specific polyimide resin and a swelling agent for swelling, and applying the film-forming stock solution on a supporting substrate. In a method for producing a porous membrane comprising a step and a step of coagulating the same in a coagulating solvent, the film-forming stock solution contains 20 to 30% by weight of a polyimide resin, and contains the organic solvent and the swelling agent. Weight ratio is 50: 50 to 60:40. |
