From: Covalent organic framework membranes through a mixed-dimensional assembly for molecular separations
Water-selective permeation properties of the membranes. a Separation performance of the TpTGCl@CNFs-5/PAN membrane with respect to different water/alcohol systems (water concentration: 10 wt%). b Long-term separation performance of the membrane applied in a water/n-butanol system (water concentration: 10 wt%; operating temperature: 80 °C). c Comparison of the water/n-butanol separation performance of the TpTGCl@CNFs-5/PAN membrane and the representative membranes in the literatures. d A schematic diagram of the transport behavior of liquid molecules across the membrane. Error bars represent standard deviations for 3 measurements
