Patent ID: 11192098

Abstract:
A method for manufacturing an ion exchange membrane is provided. The method for manufacturing an ion exchange membrane, according to one embodiment of the present invention, comprises the step of electrospinning a support fiber producing solution and an ion exchange fiber producing solution respectively to prepare a laminate in which a support fiber mat consisting of a support fiber and an ion exchange fiber mat consisting of an ion exchange fiber are alternatively laminated. According to the present invention, it is possible to simply control factors, such as the thickness, electroconductivity and mechanical strength of the membrane, and the diameter/ratio of a pore, etc. to be suitable for the use of ion exchange membrane during the manufacturing process, to simplify the manufacturing process. As such, the ion exchange membrane manufactured by the method can be utilized as a universal ion exchange membrane which has a large ion exchange capacity, a small electrical resistance, and a small diffusion coefficient as well as excellent mechanical strength and durability.
