The increasingly severe plastic pollution has urged an inevitable trend to develop biodegradable products that can take over synthetic plastics. As one of the most abundant natural polymers, polysaccharides are ideal candidate substitute rigidity polysaccharide chains principally allows for high strength and stiffness their materials, however, challenges facile orientation in material processing. Here, a general hydrogen bond-mediated plasticization strategy regulate isotropic sodium alginate (SA) highly ordered state is developed, plastics with performances fabricated. It revealed hydroxyl groups glycerol modulate viscoelasticity SA solids by forming strong bonds chains, achieving large stretchability at solid content. Highly orientated films exhibit superior tensile 575 MPa toughness 60.7 MJ m

Hydrogels have emerged as promising candidates for anticounterfeiting materials, owing to their unique stimulus-responsive capabilities. To improve the security of encrypted information, efforts are devoted constructing transient hydrogels with a dynamic information display. However, current studies design such hydrogel materials inevitably include sophisticated chemistry, complex preparation processes, and particular experimental setups. Herein, facile strategy is proposed realize by bivalent metal (M

Abstract Smart thermal emission, which is response to external stimuli, has provided an unparalleled approach exploiting optical devices that allows for tunable photon radiance. Here, of implementing information encryptions using a smart emission material exhibits non‐volatile, multifunctional, and on‐chip‐integrable properties reported. The bilayer structure, consisting tungsten (W)‐doped vanadium dioxide (VO 2 ) thin film layer self‐assembled polystyrene (PS) microsphere layer. Significant differences between the phase transition temperatures differently doped VO films enable reconfigurable in heat. Levels recorded by patterning these are thus encrypted thermo‐radiatively. Additionally, structural color PS layer, as result photonic crystal bandgap effect, shades encoded patterns from visible observation, provides anti‐counterfeiting function. Notable observation angle independence device‐friendly encoding processes also demonstrated. Based on thermo‐tunable characteristics, concept multilevel data encryption via infrared radiation detection, temperature dependence, anti‐counterfeiting, realized material.

Abstract Soft‐lithography is widely used to fabricate microstructured surfaces on plastics and elastomers for designable physical properties such as wetting adhesions. However, it remains a big challenge construct high‐aspect‐ratio microstructures the surface of hydrogels due difficulty in demolding from gel with low strength stiffness. Demonstrated here engineering tough by soft‐lithography form well‐defined micropillars. The mechanical poly(acrylamide‐ co ‐methacrylic acid) dense hydrogen‐bond associations severely depend temperature, Young's modulus increasing 8.1 MPa at 15 °C 821.8 −30 °C, enabling easy temperatures. Arrays micropillars are maintained gel, can be room temperature when restores soft stretchable. hydrogel also exhibits good shape‐memory property, favoring tailoring morphology switchable tilt angle Consequently, shows tunable adhesion properties, manifested varying contact angles strengths. These tuned geometry arrangement This facile strategy harnessing viscoelasticity supramolecular should applicable other materials, broaden their applications biomedical fields.

Abstract Reconfigurable and tunable holograms hold significant practical value in the fields of anti‐counterfeiting, optical security, information display due to their ability reprogram holographic patterns create variable visual effects. However, current encryption techniques face challenges achieving rapid encryption/decryption ensuring consistent methods. In this study, a method for producing reconfigurable hologram utilizing deformation recovery properties micropillars response liquid is demonstrated. Micron‐scale are fabricated using femtosecond laser two‐photon polymerization. By exploiting capabilities with specific pitches aspect ratios liquids, micropillar structures combined construct holograms. The encrypted pattern only readable following immersion alcohol irradiation. proposed offers facile, reversible, reusable, solution encryption, potential anti‐counterfeiting security.
