Vat Photopolymerized HEMA/HEA Hydrogels for Solvent‐Responsive Transparency and Optical Encryption

open access: yesAdvanced Optical Materials, EarlyView.
Vat‐photopolymerized HEMA/HEA hydrogels exhibit reversible transparency‐opacity switching via hydration‐induced microphase separation and solvent exchange. The printed materials enable hydration sensing, optical encryption, and information storage, while maintaining high ductility and reversible rheology.
