Abstract

Method for preparing a filtration membrane and a filtration membrane prepared by the method. According to one embodiment, the method involves casting a polymer solution onto a porous support to form a coated support. The coated support is then quenched to form a membrane/support composite, and the membrane/support composite is then dried. Next, a first end of a first piece of adhesive tape is applied to the membrane side of the composite, and the second end of the first piece of adhesive tape is applied to a first rotatable winder. In addition, a first end of a second piece of adhesive tape is applied to the support side of the composite, and the second end of the second piece of adhesive tape is applied to a second rotatable winder. The two winders are then rotated so as to pull apart the membrane from the support.
