Topological isomerization unlocks exceptional elasticity and strength of cellulosic triboelectric aerogels (opens in new tab)

Aerogel materials often aim for high elasticity, which typically compromises strength. This challenge in balancing elasticity and strength constrains their applications in wearable circuits, intelligent robots, and flexible sensors. This study presents a topological isomerization strategy based on molecular chain rearrangement to enhance both the elasticity and strength of cellulosic triboelectric aerogels. During the molecular chain rearrangement, ethylenediamine forms competitive hydrogen b...
