摘要： A method for manufacturing a porous membrane and the porous membrane manufactured by the same are provided to manufacture a porous membrane having pores equally formed in regular size in a simple process according to electric spinning, and recycle a collector solution to regularly maintain a temperature, concentration, and pH of the collector solution. An electric charge is applied to a high polymer spinning solution supply container(1) through a high voltage generator(A). A predetermined amount of a high polymer spinning solution is discharged through a nozzle(2) attached to the high polymer spinning solution supply container. The discharged spinning solution is changed into jet stream(4) by electric force after forming a Taylor cone. The formed jet stream is immersed by a collector solution(B) contained in a collector container to which a high voltage is applied, so as to form a porous membrane on a surface of the collector solution. The porous membrane is separated from the collector solution by a base material(8) passing through the collector solution. The separated porous membrane is squeezed, dried, and wound. A predetermined amount of a collector solution is supplied to the collector container while discharging a predetermined amount of a collector solution from the collector container so as to regularly maintain surface height of the collector solution in the collector container. A temperature, concentration, and pH of the discharged collector solution are controlled to be supplied to the collector container again.
