Ionic Liquid/Water Binary Solvent Anti-Freezing Hydrogel for Strain and Temperature Sensors

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(4), P. 5208 - 5216

Published: Jan. 18, 2024

Hydrogels are widely applied in the flexible wearable electronic devices field owing to their skin-like stretchability, superb biocompatibility, and high conductivity retention under mechanical deformations. Nevertheless, hydrogels prone freezing at low temperatures losing water temperatures, which seriously limits practical applications. Herein, a binary solvent system of ionic liquid (1-ethyl-3-methylimidazolium chloride) was prepared endow hydrogel (0.28 S m–1 25 °C), transparency (94.26%), superior tolerance (−50 °C). The multiple hydrogen bonds formed among polymer chains, water, liquids significantly improved properties hydrogel, enabling excellent tensile (strain >1800%) durability (1000 times 100% strain). Moreover, further assembled into dual-response sensor, exhibited satisfactory sensitivity both tension (gauge factor = 2.15 200% strain) temperature (temperature coefficient resistance −1.845%/°C) can be for human motion body monitoring. This study provides versatile method preparing multifunctional with wide range applications lays groundwork movement detection smart health care.

Grafted MXene Assisted Bifunctional Hydrogel for Stable and Highly Sensitive Self‐Powered Fibrous System

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(24)

Published: Feb. 21, 2024

Abstract Achieving highly efficient self‐powered fibrous sensing systems is desirable for smart electronic textiles but remains a great challenge. Here, bifunctional hydrogel proposed by introducing of polyacrylic acid grafted MXene (MXene‐g‐PAA) into polyacrylamide/chitosan, achieving high‐sensitivity sensor and stable electrolyte battery. The MXene‐g‐PAA flakes act as ion transport “highway”, significantly enhance ionic conductivity, thereby increasing the sensitivity sensors facilitating Zn 2+ diffusion in Zn‐ion battery (ZIB). rich hydrogen bonding network improves its mechanical properties limits water molecule movement, thus reducing side reactions prolonging stability ZIB. As result, exhibits high strain (gauge factor 2.4) with wide detection range (0–800%), capacity (353 mAh cm −3 ) long cycling (400 cycles). hydrogel‐based ZIB can be easily integrated flexible system, which effectively detects human movement 3D ball motion. system will shed light on development next‐generation textiles.
