Stable Flexible Electronic Devices under Harsh Conditions Enabled by Double-Network Hydrogels Containing Binary Cations

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(6), P. 7768 - 7779

Published: Jan. 31, 2024

Hydrogels are increasingly used in flexible electronic devices, but the mechanical and electrochemical stabilities of hydrogel devices often limited under specific harsh conditions. Herein, chemically/physically cross-linked double-network (DN) hydrogels containing binary cations Zn2+ Li+ constructed order to address above challenges. Double networks chemically polyacrylamide (PAM) physically κ-Carrageenan (κ-CG) designed account for robustness while endow with excellent ionic conductivity outstanding environmental adaptability. Excellent (25 °C, 2.26 S·m–1; −25 1.54 S·m–1) have been achieved. Utilizing DN as signal-converting materials, we fabricated mechanosensors. High gauge factors (resistive strain sensors, 2.4; capacitive pressure 0.82 kPa–1) highly stable sensing ability Interestingly, zinc-ion hybrid supercapacitors electrolytes achieved an initial capacity 52.5 mAh·g–1 at a current density 3 A·g–1 retention rate 82.9% after 19,000 cycles. Proper working subzero conditions charge–discharge more than cycles °C demonstrated. Overall, provided promising materials high-performance
