中文摘要： 电致变色器件通过人为改变自身颜色，对光线选择性地吸收和透过，从而调节透过器件的可见光或热辐射的强弱，将其作为变色窗可调控建筑、车辆等内部光线、温度等。目前所研究的电致变色器件变色波段仅限于可见或近红外区域，变色范围单一，难以同时对可见光或热辐射进行有效的调控。本项目就利用阴极变色材料WO3配以阳极变色材料开发出一种全波段电致变色器件，拟解决以下问题：（1）WO3红外波段电致变色效应的维持；（2）配对电极可见光波段电致变色效应的维持。本课题提出的半固定半游离的结构引入了可控的阳极电致变色材料，在解决以上问题的同时，对器件的结构进行优化，还可以简化器件制备工艺。

英文摘要： Electrochromic device (ECD) can change color and adjust transmit visible light or thermal radiation intensity by artificially. They could be used as a window to regulate internal light or temperature of construction, vehicles and other, etc. Up to now, the wave band of ECD’s color was limited to a single color range, the visible or near infrared region. The project aims at development of a full band ECD on the use of cathode WO3 and anode small organic electrochromic materials, so as to address the following issues: (1) how to maintain infrared color change effect of WO3; (2) how to maintain visible discoloration of the anode materials at the same time. Semi-fixed semi-free structure ECD of the issue raised by the introduction of a controlled anodic electrochromic material, which could solve the above problems at the same time and also simplify the preparation process.
