PURPOSE: A method for manufacturing a polyamideimide-based porous membrane is provided to prepare a polymer solution based on polyamideimide and a pore adjusting agent and to implement a drying, a solidifying, and a thermally treating process. CONSTITUTION: A method for manufacturing a polyamideimide-based porous membrane includes the following: a polymer solution, obtained by dissolving a polar solvent, polyamideimide, and a pore adjusting agent, is applied on a support for form a polymer membrane; pores are formed on the upper side of the polymer membrane; the polymer membrane is dried at a temperature of 50 to 100 degrees Celsius to eliminate the solvent; the polymer membrane is precipitated in the solidifying bath to be solidified, and the polymer membrane is separated from the support; and the polymer membrane is cured at a temperature of 150 to 300 degrees Celsius. |
