Harnessing Chain Mobility via Protonation for Tough and Isotropic Hydrogel

Advanced Materials, EarlyView.
A protonation‐guided strategy enables ultra‐tough, isotropic PVA hydrogels by temporarily unlocking chain mobility via acidification and fixing homogeneous networks through salting‐out. The resulting materials simultaneously achieve high strength, extreme stretchability, and record‐level toughness, offering a generalizable route toward robust hydrogels
