电致变色智能窗的设计组装与性能评价

基于国内外最新研究文献系统论述了电致变色智能窗的设计、结构、性能评价,总结了智能窗中所使用的各层材料,展望了智能窗的发展及应用前景.指出具有双电致变色膜层的互补型结构智能窗不仅大大简化了制作工序,而且性能也优于传统五层型智能窗和无离子储存对电极层的四层型智能窗.智能窗中的2种关键组分是电致变色层和电解质层,色彩丰富易于成型加工的聚合物电致变色材料以及离子导电率较高、温度变化范围较宽的锂离子聚合物电解质材料是未来电致变色智能窗的首选材料.

Design, Assembly and Performance Evaluation of Electrochromic Smart Windows

The design, structure and performance evaluations of electrochromic smart windows are systematically discussed based on the latest literature. Major materials used for smart windows are summarized. And some discussions are held about the future prospects of smart windows. It is pointed out that the smart windows with two electrochromic films greatly simplify the procedure of fabrication and exhibit better performance than the traditional five- or four-layer devices working in absence of specific ion storage counter electrode. Electrochromic materials and electrolyte play an important role in the materials used in smart windows. Polymer electrochromic materials have good coloration efficiency and processibility, and polymer electrolyte containing lithium ions can give good ionic conductivities and wide range of application temperature. Both of them are preferentially suitable for constructing smart windows.
