摘要

信息安全是维护社会稳定、保障国家安全和促进人类文明发展的重要基础，其核心需求推动了防伪材料及相关技术的创新突破。传统防伪材料依赖静态信息存储，难以应对复杂伪造技术的挑战。智能聚合物凝胶凭借对外界刺激(光、热、化学信号等)的颜色变化和形状变形响应，为动态信息存储与高等级防伪提供了新范式。本文概述了聚合物凝胶基信息存储材料在防伪领域的最新研究进展：首先简要介绍防伪材料的发展背景和智能凝胶材料的独特优势；随后重点阐述基于化学色和物理色智能凝胶的制备方法，解析其加密/解密机制；进一步探讨从单色到多色、从单维到多维的防伪模式升级发展；最后总结当前面临的稳定性、规模化等挑战，并展望其与4D打印、多功能集成等技术结合的未来发展方向。本文旨在为智能防伪材料的设计与应用提供理论指导，推动信息安全技术的创新发展。

Abstract

Information security is crucial for safeguarding human life

social stability and national security. This importance has accelerated the development of anti-counterfeiting materials and related technologies in recent years. Conventional anti-counterfeiting materials rely on static information storage

which often fails against increasingly advanced counterfeiting methods. In contrast

smart polymer gels provide a new approach through dynamic responses. These gels can change color or shape when exposed to external stimuli

such as light

heat

or chemical signals

enabling dynamic information storage and enhanced anti-counterfeiting. This review highlights the recent progress in polymer gel-based materials for anti-counterfeiting applications. It begins with a brief overview of the development of anti-counterfeiting materials and the distinctive advantages of smart gels. The article further elaborates on the preparation methods for smart gels based on chemical colorants and structural colors

along with an analysis of their encryption and decryption mechanisms. It also explores the advancement from single-color to multi-color and single-dimensional to multi-dimensional anti-counterfeiting strategies. Current challenges

such as improving stability and scalability

are also discussed. Future prospects

including integration with 4D printing and multifunctional systems

are discussed. This review aims to offer theoretical guidance for designing and applying intelligent anti-counterfeiting materials to promote innovation in the field of information security technology.
