| titleOfInvention | Method for producing asymmetric polyimide separation membrane |
| abstract | (57) [Summary] [PROBLEMS] To manufacture an asymmetric polyimide separation membrane, Improves the efficiency of phase inversion, enables adjustment of the separation membrane structure, The solvent resistance of the separation membrane can be improved. SOLUTION: A polyamic acid solution is immersed in a poor solvent, A method of producing a separation membrane by a phase inversion method, a method of producing a polyimide separation membrane by imidating the separation membrane at a high temperature, and partially heating the polyamic acid solution before immersing it in a poor solvent. To imidize. Accordingly, the time required to manufacture the separation membrane by the phase inversion method can be shortened, so that the productivity can be improved. Also, By adjusting the imidation ratio, the membrane structure can be formed into an asymmetric structure, and the solvent resistance of the separation membrane can be improved. |
