Utilizing pore and interlayer engineering within nanoconfined interlaminar channels represents an ingenious approach to design highly permselective MXene (Ti3C2TX) membranes. Herein, the tannic acid (TA) etched ZIF-8 (TZIF-8) nanocrystals with hollow structures were effectually inserted into spacing of First, density functional theory (DFT) results demonstrated reaction mechanism between TA ZIF-8. Then, underlying enhanced water-adsorptive properties for MXene/TZIF-8 membrane was due higher binding energy water/TZIF-8 system than that water/ZIF-8 system, elucidated by molecular dynamic simulation. Furthermore, low mass transfer resistance abundant pathways comprehensively proved various experimental conclusions, characterizations simulation calculations. As a result, optimal exhibited high water permeance concurrently satisfactory separation efficacy toward oil/water emulsions. This work is anticipated deepen comprehension high-efficiency transport along interbedded nanochannels in

A Bioinspired Capillary Force‐Induced Driving Strategy for Constructing Ultra‐Low‐Pressure Separation Membranes

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(24)

Published: March 17, 2023

Abstract The development of low‐pressure or pressureless self‐driven membranes is important for saving energy and overcoming the critical trade‐off effect in membrane separation processes. However, conventional rely on gravity, which effective large‐sized materials but still ineffective fine small molecules. Herein, inspired by capillary that exists nature, a force‐induced membrane‐driving strategy at ultra‐low pressures demonstrated. Hydrophilic nanoparticles are prepared cross‐linking reaction between tannic acid 3‐aminopropyltriethoxysilane then introduce them into pores to simulate sand accumulation with an aim generate force. used pressure separation. Interestingly, it found has excellent performance dye/salt mixtures (dye rejection > 99%, salt < 10%) high permeate flux (160 L m −2 h −1 ) under near “zero pressure” conditions. Moreover, structural stability verified. Introducing forces as autonomous driving force can be promising universal approach added up toolbox efficient preparation membranes.
