中文摘要： 无论在军事上还是民用领域，红外探测都扮演着不可或缺的角色。目前的红外探测仪器，存在体积大、生产成本高等问题，影响其广泛应用。一个重要原因是，探测仪中的遮光板目前都是通过机械方式控制的，结构复杂而且价格昂贵。共轭高分子电致变色材料可以通过外在电讯号的改变其特征吸收，特别是在红外波段的光吸收率变化幅度很大。而且，它具有机械电子部件无法比拟的体积小，加工方便和成本低等优点。但是，目前聚合物材料在对比度，响应时间和稳定性方面还需提高。本项目拟开发新型共轭聚合物，通过结构的优化，提升材料的上述性能，满足实际应用中对材料的要求。不仅可以降低红外仪的体积和成本，而且更加容易加工成不同的形状用于孔径成像。对这类电致变色材料和器件加工研究，可以为解决下一代红外探测中的核心问题提供新思路和新方法。

英文摘要： Present optics in IR imaging devices are hindered by costly, slow, bulky, mechanical components centered around cooling the entire system. Examples of current systems include: relatively bulky high magnification, helmet-mounted sensors that require large lens and telescope configurations, noisy mechanical shutters which limit the usefulness of many imaging systems in covert applications, expensive and bulky electronics required to mitigate focal-plane array (FPA) saturation effects (i.e., blooming) in all-weather applications, and bulky filters that are necessary to improve imaging contrast through haze and at dusk. The drive to reduce system size, weight and power consumption, while increasing the resolution and format of infrared imaging systems poses new and challenging performance requirements. Current efforts to address many of these challenges including development of light weight, fast, non-moving components have been focused on leveraging established micro-electro-mechanical systems (MEMS) approaches. However, development of reliable MEMS-based technologies has proven to be expensive, time-consuming and processing intensive. Herein, we propose to build and characterize conformal, polymer-based devices that can be fabricated directly onto pre-existing optical elements and dynamically alter the flux of i
