Counterfeiting remains a persistent global challenge, and current anti-counterfeiting technologies are often constrained by single-stimulus responsiveness and poor environmental compatibility at the end-of-life of devices. Herein, a printable, ultra-fast, degradable, and multi-stimulus anti-counterfeiting (MSAC) device based on spectrally selective MXene-TEMPO-oxidized cellulose nanofiber (TOCNF) inks is developed, enabling high-resolution patterning and reversible information encryption/decryption through screen-printing techniques. TOCNF establishes robust interfacial interactions with MXene nanosheets, forming a hydrogen-bonded network that significantly enhances the viscoelasticity and nanomechanical properties of the anti-counterfeiting layer. The resulting MSAC device demonstrates excellent infrared stealth performance in the mid-infrared range, making it suitable for high-security identity verification. Furthermore, it offers reversible information encryption, triggered by light or electrical stimuli in the UV–vis-NIR range via efficient photothermal and electrothermal conversion, enabling dynamic and multi-modal authentication. Notably, the device exhibits eco-friendly decomposition into non-toxic products by ultrasonic sonochemical treatment in hydrogen peroxide (H₂O₂) with only 200 s, representing the record high degradation rate reported among MXene-based functional materials. This work paves the way for developing multi-stimulus functional materials for the printable, sustainable, and biocompatible anti-counterfeiting applications.
