The structural color of photonic crystals has garnered considerable attention in the domains coded information security and anticounterfeiting technology mechanisms. However, most alterations induced by hinge on dynamic regulation triggered external stimuli, limiting their utility static settings. Herein, polyvinylidene fluoride (PVDF) films with a bilayer inverse opal structure are engineered to enable display concealment messages contingent observer's viewing angle. inherent attributes PVDF polymer confer upon high stability flexibility, as confirmed through curling, friction, tensile tests. Notably, upper layer serves background, while bottom functions pattern these films. Owing angle dependence shielding effect background layer, remains concealed at angles above 45° becomes visible below 30°. These have been adapted for use touch-tone numeric keypad protective patches optimizing particle size thickness parameters. According findings, systems based highly ordered crystal structures offer substantial promise applications environments.

Increasing modal variations of stimulus-responsive materials ensure the high capacity and confidentiality information storage encryption systems that are crucial to security. Herein, thermochromic perovskite microcapsules (TPMs) with dual-variable quadruple-modal reversible properties designed prepared on original oil-in-fluorine (O/F) emulsion system. The TPMs respond orthogonal external UV thermal stimuli in four switchable modes exhibit excellent thermal, air, water stability due protection perovskites by core-shell structure. Benefiting from high-density TPMs, multiple encryptions decryptions demonstrated. Moreover, a set devices assembled for multilevel By taking advantage as "private key" decryption, signal can be identified corresponding binary ASCII code converted real message. results demonstrate breakthrough well system based TPMs.

Abstract Low‐swelling polymers (LSPs) generally refer to materials with a low solvent absorption ratio or volume expansion rate at swelling equilibrium. LSPs exceptional responsiveness could be upgraded smart sensors structural color self‐reporting by bridging photonic crystals (PCs). Based on the regulation of effective refractive index, lattice spacing, order‐disorder arrangement nanostructures, and incident/detection angle, feedback crystal (SPCSs) can quantitatively visually reveal stimulus, which greatly promotes interdisciplinary development nanophotonic technology in fields chemical engineering, science, engineering mechanics, biomedicine, environmental etc. Herein, clarify role structures polymer molecules high‐performance SPCSs, LSP‐based SPCSs are summarized discussed, including general mechanisms, change strategies, design, typical functional applications. It aims figure out combination rule between PC LSPs, optimize design structures, expound corresponding sensing inspiring fabrication next‐generation SPCSs. Finally, perspectives future applications also presented. is believed that multifunctional tools for numerous future.
