Preparation method of ion exchange fabric membrane

The invention discloses a preparation method of an ion exchange fabric membrane, and belongs to the field of membrane material preparation. The method comprises the steps that a copolymer containing ion exchange groups is prepared through a free radical solution polymerization method, an electrospinning liquid is electrospun to the surface of a fabric obtained after pre-grafting polymerization treatment through an electrostatic spinning technology, and then crosslinking is carried out by using a cross-linking agent to obtain the homogeneous ion exchange fabric membrane. The obtained ion exchange membrane is high in mechanical strength, large in ion exchange capacity, free of environmental pollution in the preparation process and wide in application prospect. 本发明公开了一种离子交换织物膜的制备方法，属于膜材料制备领域。本发明用自由基溶液聚合法制备了含有离子交换基团共聚物，再通过静电纺技术将电纺液电纺至预接枝聚合处理的织物表面，然后用交联剂交联获得均相离子交换织物膜。所得离子交换膜力学强度高，离子交换量大，制备过程无环境污染，具有广阔的应用前景。
