Organic ceramic composite film as well as preparation method and application thereof
The invention belongs to the field of lithium ion resource extraction. According to the organic ceramic composite film and the preparation method and application thereof, the composite film is formed by chemically bonding an intrinsic microporous polymer layer (PIMs layer) on a porous aluminum oxide substrate, so that the composite film has excellent mechanical stability, lithium selectivity and film flux; the disadvantages and problems when a single inorganic ceramic membrane or an organic polymer membrane is used as a cation exchange membrane are solved; meanwhile, the adhesiveness and binding force of the PIMs layer and the substrate are improved in a chemical bonding mode, the overall stability of the composite film is further improved, and the service life of the composite film is further prolonged.
本发明属于锂离子资源提取领域。本发明提供了一种有机陶瓷复合薄膜及其制备方法与用途，本发明通过在多孔氧化铝基底上通过化学键合自具微孔聚合物层(PIMs层)而形成复合薄膜，使得该复合薄膜得以兼顾优异的机械稳定性、锂选择性及膜通量，解决使用单一的无机陶瓷薄膜或有机聚合物膜作为阳离子交换膜时劣势和问题；同时，通过化学键合的方式提升PIMs层与基底的附着性和结合力，进一步提升复合薄膜整体的稳定性和使用寿命。
