PURPOSE: A method for selecting a polymeric separation membrane material suitable for a stretching process is provided to select easily a membrane material without performing a pre-manufacturing process of a polymeric separation membrane, and to form pores effectively. CONSTITUTION: A method for selecting a polymeric separation membrane material suitable for a stretching process includes a step for determining a polymeric material showing a strain hardening region and a yield point on a stress-strain curve. A manufacturing method of a porous polymeric separation membrane based on a stretching process includes a step for drawing the polymeric material on the stress-strain curve. |
