摘要
采用化学法合成聚苯胺(PANI),在柔性不锈钢丝网上进行涂覆,成功制备了反射型柔性变色器件.测试并获取了不同电位下(即不同的掺杂态)的紫外-可见光全反射光谱,比较确定了该变色器件合适的使用电压为+0.7 V和-0.6 V.并在选定的使用电压下对变色器件进行测试,讨论了工作电极上PANI用量、电解质层用量和离子储存层用量对变色器件的显色影响.结果显示,随着工作电极PANI用量的增加,翠绿亚胺盐固有的墨绿色会对变色器件的显色造成影响,使变色器件的光反射特性降低;随着电解质层用量的增加,变色器件的反射率大致呈先增加后减小的趋势;随着离子储存层用量的增加,工作电极PANI掺杂或脱掺杂的程度也会增加,使得变色器件的反射率增加,反射特征越明显.
Polyaniline(PANI) was synthesized by chemical polymerization,and coated on the flexible stainless wire,and then a flexible reflective electrochromic device(ECD) based on PANI was successfully assembled.The electrochromic devices were measured in different fixed voltages,and scanned by the ultraviolet spectrometer,obtaining a UV-Visible light total reflectance spectrum.It was found the comparatively appropriate voltages for devices were +0.7 V and-0.6 V.The effects of the PANI content on the working electrode,the amount of the electrolyte layer and the amount of ion storage layer on the reverse electrode on the performance of electrochromic devices were studied.The results show that the inherent green of the emeraldine salt could affect the color characteristic of the device with the increase of the amount of PANI on the working electrode,making the light reflection of the device reduced.The reflectivity of the device generally increased first and then decreased with the increase of the amount of the electrolyte layer.The reflectivity of the device increased with the increase of the amount of ion storage layer on the reverse electrode and also the doped or dedoped level of the PANI on the working electrode would increase,and also the reflectible features would be more obvious.
