To address the limitations of traditional anti-counterfeiting materials, including low responsiveness, easy replication, and poor environmental stability, a fluorescein (Flu) loaded zeolitic imidazolate framework (ZIF-8) photothermal-responsive anti-counterfeiting hydrogel was designed. Flu was first confined within ZIF-8 via a one-pot method and then embedded into a polyacrylamide\/lauryl methacrylate (PAM\/LMA) network. This hydrogel emits intense green luminescence under 365 nm UV illumination. Its fluorescence can be quenched by Fe3+ and recovered upon exposure to PO43\u2212, which endows the material with rewritable data storage capacity. Sodium dodecyl sulfate (SDS) and sodium chloride (NaCl) in the hydrogel provide a temperature-dependent reversible transparency transition, allowing multi-level information encryption through the synergistic action of temperature, ions, and UV light. In addition, the hydrogel also features low toxicity, degradability, and an environmentally friendly solvent-free synthesis. This work demonstrates a multi-stimuli responsive strategy that overcomes the limitation of traditional single-responsive anti-counterfeiting materials, offering a promising approach for the design of rewritable and eco-friendly intelligent anti-counterfeiting systems and serving as a reference for the development of multifunctional responsive materials.<\/jats:p>","DOI":"10.3390\/gels12070634","type":"journal-article","created":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T06:49:36Z","timestamp":1784184576000},"page":"634","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A
