Tóm tắt

 Photochromic inks have been a significant certification approach to improve document anticounterfeiting efficiency. However, the weak photostability and poor durability are two of their major shortcomings. Herein, this article details the development of a photochromic and self-healable hydrogel for advanced anticounterfeiting uses. When immobilized in tricarboxylic cellulose (TCC), electrospun glass nanofibers (90-170 nm) and lanthanide-activated strontium aluminate nanoparticles (LSAN
