摘　　要：基于传统储存介质的信息常常以静态形式显现,无法面对当下伪造、仿制技术带来的挑战。因此,荧光水凝胶——一类具有优异的刺激响应发光特性,结构和功能易于设计和调控的智能响应类“软材料”,由于其能够在特定的外界刺激下呈现颜色的变化或者形状的改变,因而在信息安全和防伪领域引起了广泛的研究兴趣。本文概述了荧光水凝胶基信息储存材料的构筑历程,详细归纳了信息加密与保护模式从单级加密到多级加密(三维加密平台和迷惑信息加密)模式,再到具有时变效应的动态加密模式的阶段性演变。最后,就荧光水凝胶的构筑方法和信息加密应用方面,深入讨论了其面临的挑战、机遇和未来发展前景。本综述旨在促进荧光水凝胶基信息储存材料及其加密性能的进一步发展,为未来更智能、安全型信息加密体系的研发提供思路。Traditional storage media presents information in a static form,making it vulnerable to counterfeiting and imitation.To address this issue,researchers have turned to fluorescent hydrogels,a type of“soft material”that exhibits excellent luminescence characteristics and can be easily designed and regulated.These materials are of particular interest in the field of information security and anticounterfeiting due to their ability to change color or shape in response to specific external stimuli.By incorporating fluorescent hydrogels into products or packaging,it is possible to create dynamic and interactive features that are difficult to replicate or manipulate,offering a more secure solution than traditional static storage media.Based on these,this literature summarized the construction progress of fluorescent hydrogel-based information storage materials,concluded the phased evolution in the patterns of information encryption and protection varying from the single level encryption to the multilevel encryption(3D encryption platform and confusing information encryption),and then to the dynamic encryption patterns with time-varying effects.Last but not least,the challenges,opportunities and future development prospects of fluorescent hydrogels were discussed in terms of the construction methods and information encryption applications.The purpose of this review was to promote the further development of fluorescent hydrogel-based information storage materials and their encryption properties,providing insights for the future development of more intelligent and secure information encryption systems.
