| titleOfInvention | Manufacturing method of composite porous membrane |
| abstract | The present invention provides a method for producing a composite porous membrane which can achieve stable film quality and desired hollow shape by controlling the entry of the film-forming resin solution into the hollow portion of the hollow reinforcing supporter. The method for producing a composite porous membrane of the present invention comprises the steps of attaching a film-forming resin solution to the outer circumferential surface of the hollow reinforcing support body to form a membrane intermediate, attaching the coagulating liquid to the outer circumferential surface of the membrane intermediate, and the outermost surface of the coagulating liquid. And coagulating the coagulating solution along the outer circumferential surface of the membrane intermediate so that at least a part of the circumferential direction in the circumferential direction is a free surface, and solidifying the film-forming resin solution attached to the outer circumferential surface of the hollow reinforcement support. |
