High-performance solid-state proton gating membranes based on two-dimensional hydrogen-bonded organic framework composites

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 17, 2025

Biological ion channels exhibit strong gating effects due to their zero-current closed states. However, the capabilities of artificial nanochannels have typically fallen short biological channels, primarily owing larger nanopores that fail completely block transport in off-states. Here, we demonstrate solid-state hydrogen-bonded organic frameworks-based membranes achieve high-performance ambient humidity-controlled proton gating, accomplished by switching pathway instead relying on conventional blockage/activation effects. Density functional theory calculations reveal reversible formation and disruption humidity-induced water bridges within frameworks facilitates mode from adsorption site hopping Grotthuss mechanism. This transition, coupled with introduction bacterial cellulose enhance desorption/adsorption clusters, enables us a superior ratio up 5740, surpassing state-of-the-art devices. Moreover, developed membrane operates entirely principles, rendering it highly versatile for myriad applications environmental detection human health monitoring. study offers perspectives design efficient systems.

Advanced Science, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 11, 2024

Membranes with switchable wettability, solvent resistance, and toughness have emerged as promising materials for separation applications. However, challenges like limited mechanical strength, poor chemical stability, structural defects during membrane fabrication hinder their widespread adoption. Covalent organic frameworks (COFs), crystalline constructed from molecules connected by covalent bonds, offer a solution due to high porosity, customizable properties. The ordered structures functionality provide COFs lightweight framework, large surface area, tunable pore sizes, which attracted increasing attention applications in separations. Recent research has extensively explored the preparation strategies of COF membranes various processes. This review uniquely delves into influence techniques, including interfacial polymerization, layer-by-layer assembly, situ growth, on thickness performance. It comprehensively explores design potential these methods, particular focus gas separation, oil/water nanofiltration. Furthermore, future opportunities, within this field, directions development are proposed.

Ion‐Transport Kinetics and Interface Stability Augmentation of Zinc Anodes Based on Fluorinated Covalent Organic Framework Thin Films

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 13, 2024

Abstract Zinc (Zn) emerges as an ideal anode for aqueous‐based energy storage devices because of its safety, non‐toxicity, and cost‐effectiveness. However, the reversibility zinc anodes is constrained by unchecked dendrite proliferation parasitic side reactions. To minimize these adverse effects, a highly oriented, crystalline 2D porous fluorinated covalent organic framework (denoted TpBD‐2F) thin film in situ synthesized on Zn protective layer. The zincophilic hydrophobic TpBD‐2F provides numerous 1D nanochannels, which facilitate hopping/transfer 2+ repel H 2 O infiltration, thus regulating flux inhibiting interfacial corrosion. resulting enabled stable plating/stripping symmetric cells over 1200 h at mA cm −2 . Furthermore, assembled full (Zn‐ion capacitors) deliver ultra‐long cycling life 100 000 cycles current density 5 A g −1 , outperforming nearly all reported materials.
