中文摘要：
铁电材料具有自发极化和双稳态记忆特性。利用铁电极化反转对空间电场进行调制，可以对某些与电荷传导或电极化有关的物理性质产生影响。电致变色是一种由于电子和离子的双注入，导致材料的光学属性（吸收率、反射率、透射率等）发生变化的特殊现象，可应用于光学调节、显示和全天候隐形等高新领域。本课题提出在电致变色薄膜器件中引入透明铁电层、利用铁电极化控制和提高电致变色性能的新思路。拟采用脉冲激光沉积法和溶胶-凝胶法制备铁电-电致变色复合薄膜器件，通过电学、光学分析手段研究极化对空间电场的调制作用以及对电荷注入/抽出过程动力学机制的影响。这项研究有望提高电致变色器件的综合性能，解决现有器件中响应速度慢、稳定性差、分辨率低等问题，并对深入理解电致变色现象的微观机理有着积极的意义。
