Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

Abstract As a visible light‐responsive metal‐free polymer semiconductor, graphitic carbon nitride (g‐C 3 N 4 ) has garnered increasing attention in photocatalysis but needs structural modification and functional enhancement. Recently, the rational design of ionic microenvironments (IMEs) by leveraging tunability various ions to endow catalysts with tailored functionalities been elevated hot direction. To elucidate their respective effects on g‐C , IMEs are categorized into three types, namely plasma IMEs, organic inorganic according criteria external field dependence, cation type, application scenarios. These promotions include facilitated preparation, diversified modifications, improved efficiencies. First, participate constructing functionalized microenvironment through dynamic interactions precursor during facilitating customization, crystal nucleation growth, surface performance enhancement, process cleanliness. Second, create tunable for post‐modification functioning as an electron reservoir, modifier, substrate adsorbent, stabilizer. Lastly, synergistic effect between IME they achieve targeted product regulation, enhanced chemical stability, efficient adsorption, potential fields like catalysis, energy storage, gas adsorption. Also, limitations, challenges, prospects strategies discussed, offering systematic insights IMEs‐based structure‐activity relationships 4.

Low‐Hysteresis and Tough Ionohydrogels Well‐Balanced by Water

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 24, 2025

Abstract Low‐hysteresis merits in polymeric gel materials can significantly enhance their operational reliability and service lifetime emerging applications such as smart wearable devices. However, fabricating with low hysteresis high toughness remains challenging due to intrinsic contradictory attributes, particularly ionic liquid (IL)‐based systems. Herein, a water‐mediated polymer network reorganization strategy is presented for developing tough ionohydrogels (IHGs) containing ILs, where the synergistic effect between covalent crosslinking dynamic interfacial lubrication governs exceptional performance. Water act lubricating mediator moderately attenuate interactions ILs chains, thereby enabling formation of dynamically adaptive networks that facilitate chain mobility stress redistribution. Therefore, IHGs fabricated through water content modulation achieve well‐balanced combination (2.2 MJ m −3 ) (8.1% at 400% strain). Meanwhile, prepared demonstrate superior comprehensive performance, including stretchability, excellent tensile strength, electrical conductivity, good biocompatibility, transparency. Finally, function high‐performance sensors biocompatible epidermal electrodes, real‐time health monitoring acquisition high‐fidelity electrophysiological signals. The simple overcomes traditional trade‐offs toughness, demonstrating potential real‐life scenarios.
