Abstract Ubiquitous anti‐counterfeiting materials with a rapidly rising annual consumption (over 10 m 2 ) can pose serious environmental burden. Biobased cellulosic birefringence offer attractive sustainable alternatives, but their scalable solvent‐free processing remain challenging. Here, dynamic chemical modification strategy is proposed for multi‐modal melt‐processing of birefringent eco‐friendly anti‐counterfeiting. Relying on the thermal‐activated covalent‐locking spatial topological structure preferred oriented cellulose, balances contradiction between strong confinement long‐range ordered structures and molecular motility required entropically‐driven reconstruction. Equipped customizable forms including mold‐pressing, spinning, direct‐ink‐writing, blade‐coating, exhibit wide color gamut, self‐healing efficiency (94.5%), recyclability, biodegradability. Moreover, diversified flexible elements facilitate fabrication compatibility universal techniques, thereby enabling versatile programmable The expected to provide references cellulose promote innovation in industry.

Responsive luminescent materials that reversibly react to external stimuli have emerged as prospective platforms for information encryption applications. Despite brilliant achievements, the existing fluorescent usually low density and experience inevitable loss when subjected mechanical damage. Here, inspired by hierarchical nanostructure of proteins in jellyfish, we propose a self-healable, photoresponsive elastomer based on dynamic interface-anchored borate nanoassemblies smart dual-model encryption. The rigid cyclodextrin molecule restricts movement guest molecules, enabling long room-temperature phosphorescence (0.37 s) excitation wavelength-responsive fluorescence. building reversible interfacial bonding between polymer matrix together with their nanoconfinement effect endows nanocomposites excellent performances (tensile strength 15.8 MPa) superior functional recovery capacities after Such supramolecular interfaces enable simultaneous material functionalization self-healing, paving way development advanced materials.

Luminescent encrypted labels can effectively solve the problem of counterfeiting. However, they suffer from complex design and fabrication, low space utilization, limited capacity information. Herein, we create multilayer infrared luminescent encryption using femtosecond-laser-activated Er-doped silicon. In comparison with other annealing techniques that treat whole sample at once, femtosecond lasers have a high spatial precision flexibility, which locally anneal Si, generating stable controllable multilayered photoluminescent patterns. It therefore significantly enhance security increase information storage capacity. This work demonstrates low-cost, high-capacity, high-security label great application value. Fs-laser-annealed silicon is also promising material to realize quantum light sources or gain materials for communication band.

Amid the ongoing Global Plastics Treaty, high-quality circulation of halogen-containing plastics in an environmentally sound manner is a globally pressing issue. Current chemical dechlorination methods are limited by their inability to recycle PVC at long-chain carbon level and persistence eco-toxic organochlorine byproducts. Herein, we propose click strategy for transforming waste into valuable vitrimers via one-step cascade thiol-ene reaction dynamic polymerization. Thermal activation C-Cl bonds initiates β-elimination dechlorination, while disulfide synchronously undergo homolytic cleavage, generating sulfur-centered radicals that drive precise sulfur-chlorine substitution formation networks. This achieves nearly complete chlorine extraction (93.88%) produces with tailorable mechanical reprocessing properties, spanning from soft elastomers 784% elongation rigid yield strength 34 MPa. The significant advantage this backbone protective enabling ecosystem toxicity reduced 99.51% compared widely adopted pyrolysis methods. work introduces sustainable pathway upcycling materials, marking progress chlorinated plastic recycling.
