![]() Correspondingly, problems can be caused by counterfeit information and private important information leakages 2. With the rapid development of the information age, global data storage will exceed 200 zettabytes by 2025 1, 2. Overall, TSFF capable of rewritable 2D/3D encoding will inspire the design of smart materials for high-security information carriers. This rewritable 2D/3D encoding strategy can enhance information security because only designated inspectors can decode the information by providing sequential heating for shape recovery and UV exposure. Meanwhile, the thermadapt shape-memory properties not only enables the reconfiguration of the permanent shape for creating and erasing 3D patterns, i.e., rewritable 3D information, but also facilitates recoverable shape programming for 3D encoding. The reversible photo-cross-linking of anthracene is accompanied by repeatable fluorescence-shifting and enables rewritable 2D encoding. The TSFF is based on anthracene group with reversible photo-cross-linking and poly (ethylene-co-vinyl acetate) network with thermadapt shape-memory properties. Herein, inspired by the mimic octopus capable of camouflage by changing colors and shapes, we develop a thermadapt shape-memory fluorescent film (TSFF) for integrating 2D/3D encoding in one system. However, the 2D encoding of fluorescent images poses a risk of information leakage.
