荧光水凝胶基信息储存材料的构筑及其加密性能研究进展OA北大核心CSTPCD

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 anti-counterfeiting 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.
