Pressure-driven, superfast organic solvent filtration membranes have significant practical applications. An excellent filtration membrane should exhibit high selectivity and permeation in aqueous and organic solvents to meet increasing industrial demand. Here, we report an amino functionalized boron nitride (FBN) based filtration membrane with a nanochannel network for molecular separation and permeation. This membrane is highly stable in water and in several organic solvents and shows high transport performance for solvents depending on the membranes' thickness. In addition, the FBN membrane is applicable for solute screening in water as well as in organic solvents. More importantly, the FBN membranes are very stable in acidic, alkaline and oxidative media for up to one month. The fast-flow rate and good separation performance of the FBN membranes can be attributed to their stable networks of nanochannels and thin laminar structure, which provide the membranes with beneficial properties for practical separation and purification processes.
压力驱动的超快有机溶剂过滤膜具有重要的实际应用。优秀的过滤膜应该在水相和有机溶剂中表现出高选择性和渗透性，以满足不断增长的工业需求。在这里，我们报道了一种基于氨基功能化氮化硼（FBN）的纳米通道网络过滤膜，用于分子分离和渗透。该膜在水中和几种有机溶剂中具有高度稳定性，并表现出高溶剂透过性能，这取决于膜的厚度。此外，FBN 膜可用于水相和有机溶剂中的溶质筛选。更重要的是，FBN 膜在酸性、碱性和氧化介质中稳定长达一个月。FBN 膜的快速流速和良好的分离性能归因于其稳定的纳米通道网络和薄的层状结构，这为膜提供了有利于实际分离和净化过程的特性。
