Supramolecular Zwitterionic Hydrogels for Information Encryption, Soft Electronics and Energy Storage at Icy Temperature

open access: yesAdvanced Functional Materials, EarlyView.
A series of ACHPES‐based hydrogels are developed and realizing multiple functions like anti‐fouling properties, alkali‐induced color/fluorescence‐changing ability and strain sensing. Furthermore, the hydrogels show excellent anti‐freezing performance, whose optical, mechanical and electrical properties remain stable at −47.3 °C.
