Conspectus Fluorescent polymer hydrogels (FPHs) are of significant interest for diverse
emerging applications such as visualized sensing, smart display, camouflaging skins, soft …

While photoluminescence printing is a widely applied anticounterfeiting technique, there are
still challenges in developing new generation anticounterfeiting materials with high security …

Uncovering differences between crystalline and amorphous states in molecular solids would
both promote the understanding of their structure–property relationships, as well as inform …

Fluorescent patterns showing the unique color change in response to external stimuli are of
considerable interest for their applications in anti‐counterfeiting. However, there is still a lack …

Most hydrogels become frozen at subzero temperatures, leading to degraded properties and
limited applications. Cryoprotectants are massively employed to improve anti‐freezing …

Due to their similarity to some bio‐architectures, for example, extracellular matrix, hydrogels
are considered as bio‐inspired networks with bio‐mimetic and bio‐functional properties …
