Abstract Covalent organic frameworks (COFs) have attracted great interest as advanced membrane materials due to their uniform channel structure and high porosity. In this work, COF-LZU1/PES composite membranes were prepared via interfacial polymerization (IP) process, and the thin and defectless COFs active layers were successfully grown on poly (ether sulfone) (PES) microfiltration substrates with 1,3,5-triformylbenzene (TFB) and p-phenylenediamine (PDA) as precursors. The prepared COF-LZU1/PES composite membranes exhibit a high rejection rate (>99.0%) for the dyes with molecular size above 1.5 nm and nonselective permeation for inorganic salts (

COF-LZU1/PES复合膜在微滤基材上通过界面聚合轻松制备用于染料/盐分离

摘要 共价有机骨架（COFs）由于具有均匀的通道结构和高孔隙率，作为先进的膜材料引起了人们的极大兴趣。在这项工作中，COF-LZU1/PES 复合膜通过界面聚合 (IP) 工艺制备，并且薄且无缺陷的 COF 活性层成功地生长在聚醚砜 (PES) 微滤基材上，具有 1,3,5-三甲酰苯 (TFB) 和对苯二胺 (PDA) 作为前体。所制备的 COF-LZU1/PES 复合膜对分子尺寸大于 1.5 nm 的染料表现出较高的截留率（>99.0%），对无机盐具有非选择性渗透（
