Programming Shape Memory Hydrogel to a Pre‐Encoded Static Deformation toward Hierarchical Morphological Information Encryption (Adv. Funct. Mater. 45/2022)

Morphological Information Encryption In article number 2206912, Wu, Zhang, Chen, and co-workers apply short alkyl chains modified polyvinyl alcohol as a molecular switch to control the static deformation of shape memory hydrogel. Thus, the hydrogel morphologies can be encoded with encrypted morphological information, furtherly delivering hierarchical and continuous morphological information with the assistance of programmed near-infrared light.
