氟功能化阳离子共价有机骨架吸附剂及其制备和应用,属于环境功能材料领域。吸附剂为含氟侧链iCOFs,由含氟卤代烷烃对含吡啶氮的亚胺基COFs后修饰制备而成。通过不同长度含氟卤代烷烃的后修饰,对吸附剂的表面电荷、比表面积和亲疏水性调控。在静电作用、孔道填充效应、疏水作用和氟‑氟相互作用的协同下,吸附剂对全氟及多氟烷基化合物(PFASs)表现出优异吸附性能,兼具快速吸附和高吸附容量。吸附剂在不同水质中对低浓全氟辛酸(PFOA)具有高效吸附,可广泛用于多种PFASs吸附。通过构筑多重相互作用协同的策略突破传统多孔吸附剂对单一相互作用的依赖,实现水溶性PFASs的高效吸附,在新污染物去除领域具应用前景。
