Abstract
一种用于油水分离的长链烷基菲并咪唑共价有机框架膜及其制备方法和应用，它涉及油水分离膜及其制备方法和应用。它是要解决现有的用于油水分离复合膜的制作周期长、制作繁琐、油水分离效果差的技术问题。本发明的共价有机框架膜是将长链烷基菲并咪唑共价有机框架材料覆在PVDF膜上形成的，其中共价有机框架材料的基本结构单元为：制法：先用2‑(4‑正辛氧基苯基)‑1H‑菲并[9,10‑d]咪唑‑5,10‑二胺与1,3,5‑三(4‑甲酰基苯基)苯制备长链烷基菲并咪唑共价有机框架材料；再制备成分散液，抽滤，将共价有机框架材料抽滤成膜并负载在PVDF膜上。利用该膜进行油水分离的效率为92％～98％。可用于有机分离领域。
