用于智能纺织品的柔性电致变色器件研究

Study on the preparation of flexible electrochromic devices used for intelligent textiles

柔性电致变色器件与传统电致变色器件相比具有更广阔的应用前景,制约其制备及应用的关键在于柔性透明电极的选用及器件各层材料的封装。介绍了选用ITO导电薄膜作为透明导电层,聚苯胺作为电致变色层和离子存储层,PM-MA基凝胶电解质作为离子导电层来制备对称结构的柔性电致变色器件,并对其进行电子扫描电镜、紫外光谱、循环伏安及电化学光谱等系列电化学性能测试。

Hexible electrochromie device has more wider applications compared with traditional electrochromic device. However, the selection of flexible transparent electrodes and the packaging of each layer material restrict its preparation and application. ITO conductive film would be chosen as transparent conductive layer with polyaniline used as electrechromic layer and as ion storage layer, and PMMA based gel electrolyte applied as ionic conduction layer in the preparation of the symmetric structure flexible electrochremic device. Series of electrochemical perfonnance testings are conducted by means of electronic scanning electron microscopy （sem） , ultraviolet spectrum, circulation current-voltage and electrochemical spectrum.
