Abstract
A submicron thick diboronic acid linked GOF/polyvinyl alcohol hybrid membrane was prepared for the first time. The uniform inter-spacing of the GOF membrane excludes the diffusion of large molecules based on a molecular sieving mechanism. It exhibits high stability and excellent sieving performance in solvent (≥C3) dehydration (SFs > 10,000).
摘要
首次制备了一种亚微米厚的硼酸二酯连接的氧化石墨烯/聚乙烯醇混合膜。氧化石墨烯膜均匀的间距基于分子筛机制排除了大分子的扩散。它在溶剂（≥C3）脱水方面表现出高稳定性和优异的筛分性能（分离因子>10,000）。
