Porous organic polymers (POPs) as absorbing materials have attracted increasing attention. Here, we report a new approach to prepare these polymers for selective oil absorption from oil/water mixtures. Perfluoroalkylbis(diaryldiazomethane) was synthesized and used to modify the surface of an electrospun gelatin membrane by a carbene insertion reaction, not only to immobilize the porous network morphology by cross-linking but also to introduce perfluoroalkyl groups for oil/water separation. The membrane was characterized to show its surface and bulk properties, as well as its performance for absorption capacity, selectivity, and renewability. This approach offers a new horizon in the preparation of POPs for oil/water separation.
多孔有机聚合物（POPs）作为吸收材料已引起越来越多的关注。在此，我们报告一种制备这些聚合物以从油/水混合物中选择性吸油的新方法。合成了全氟烷基双（二芳基重氮甲烷），并通过卡宾插入反应用于修饰静电纺丝明胶膜的表面，不仅通过交联固定多孔网络形态，还引入全氟烷基用于油/水分离。对该膜进行了表征，以显示其表面和本体性质，以及其吸收容量、选择性和可再生性方面的性能。这种方法为制备用于油/水分离的POPs开辟了新的前景。
