Ionoprinting controlled information storage of fluorescent hydrogel for hierarchical and multi-dimensional decryption

摘要: Information storage and corresponding encryption/decryption are highly important owing to the prevalence of counterfeit activities information leakage in current age. Herein, we propose a novel method store via controllable ionoprinting onto fluorescent hydrogel for hierarchical multi-dimensional decryption. Through incorporating pyrene moieties carboxylic groups into polymeric network, fluorescence changing shape deformation behaviors could be achieved integrated by Fe3+ ions. The diffusion ions can quench moieties, chelate with generate anisotropic structures simultaneously. Thus, quenching-based 2D actuation-based 3D hierarchically decrypted when exposed UV light being put water, respectively. Importantly, stored erased replacing H+, which allows as recyclable material. This work may provide new insights designing fabricating soft devices encryption, against rising problems counterfeiting confidential disclosure.
