Smart Adhesives with Multilevel Security Features for Real-World Anticounterfeiting Applications.

ABSTRACT: Counterfeiting in the manufacturing and publishing industries poses serious threats, including brand damage, financial losses, compromised quality, and infringement of intellectual property rights. Although existing anticounterfeiting technologies like RFID tags, QR codes, holograms, and blockchain offer protection, increasingly advanced counterfeiting methods challenge their effectiveness. Adhesives, despite being essential in manufacturing and bookbinding for their bonding and durability properties, remain underexplored as anticounterfeiting tools. This study presents a novel approach by developing glue formulations embedded with multilevel security markers for real-world applications. Hot melt adhesives are integrated with infrared (IR) emissive and up-conversion green phosphors, offeri
