Super‐Stretchable, Anti‐Freezing, Anti‐Drying Organogel Ionic Conductor for Multi‐Mode Flexible Electronics

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(41)

Published: June 9, 2023

Abstract Due to their intrinsic flexibility, tunable conductivity, multiple stimulus‐response, and self‐healing ability, ionic conductive hydrogels have drawn significant attention in flexible/wearable electronics. However, challenges remain because traditional inevitably faced the problems of losing flexibility conductivity inner water loss when exposed ambient environment. Besides, inside hydrogel will freeze at icing temperatures, making device hard fragile. As a promising alternative, organogels attracted wide they can, some extent, overcome above drawbacks. Herein, kind organogel conductor (MOIC) by self‐polymerization reaction is involved, which super stretchable, anti‐drying, anti‐freezing. Meanwhile, it can still maintain high mechanical stability after alternately loading/unloading strain 600% for 600 s (1800 cycles). Using this MOIC, high‐performance triboelectric nanogenerator (TENG) constructed (MOIC‐TENG) harvest small energy even MOIC electrode underwent an extremely low temperature. In addition, multifunctional sensors (strain sensor, piezoresistive tactile sensor) are realized monitor human motions real time, recognize different materials effect. This study demonstrates candidate material electronics such as electronic skin, flexible sensors, human‐machine interfaces.
