The present invention relates to a method for producing a filtration membrane and a filtration membrane produced by the method. According to one embodiment of the invention, the method comprises casting a polymer solution onto the porous support to form a coated support. Next, the coated support is quenched to form a membrane / support composite, and then the membrane / support composite is dried. Next, a first end of the first adhesive tape is fixed to the membrane side of the composite, and a second end of the first adhesive tape is fixed to the first rotary winder. Further, a first end of the second adhesive tape is fixed to the support side of the composite, and a second end of the second adhesive tape is fixed to the second rotary winder. The two winders are then rotated to pull the membrane apart from the support. |
