中文摘要： 本项目主要是设计与制备基于物理凝胶的光子纸材料，并研究其在隐形标记方面的性能。首先利用物理凝胶易于制备的特性，实现光子晶体材料的包覆；通过正离子化修饰，制备温度开关型光子纸材料；以二次化学聚合方法，制备多响应性光子纸材料；最后，通过在二次聚合过程施加图形掩膜实现对光子纸的隐形标记，利用扫描电镜、核磁共振、光纤光谱等表征手段，建立凝胶网络结构与响应灵敏度之间的关系。本项目以实验与理论相结合，包括材料制备改性、性能测试分析与理论研究探索三部分，希望为开发出具有多重指示功能的智能型光子晶体材料提供新思路。

英文摘要： This project is mainly focus on the design and fabrication of photonic paper materials based on physical hydrogels, and investigates their applications in invisible printings. Firstly, the physically gelated hydrogel is utilized to form a hydrogel-based photonic crystal material, by using the physical properties of the gel is easy to preparation, and a thermal sensitive photonic switch is designed by positive ionization of the hydrogel. And a second photo-polymerization is designed for the preparation of multi-responsive photonic paper materials, during the photo-polymerization, the invisible printing of photonic paper could be obtained by cover a mask with certain pattern. Scanning electron microscopy, nuclear magnetic resonance and optical fiber spectroscopy could be utilized for the characterization of the photonic paper and establish the relationship between the response sensitivity and the microstructure of the photonic paper. This proposal faces the experiment and theory, including the preparation, modification, characterization and theoretical study of the photonic paper materials, and provides new ideas for the future design and developing of intelligent photonic crystal materials with multi-sensitivity.
