在本研究中，两种导电聚合物聚苯胺（PANI）和聚（3,4-乙烯二氧噻吩）（PEDOT）被用于构建电致变色器件（ECD）。采用聚苯胺作为阳极着色聚合物，PEDOT作为阴极着色聚合物。将在570nm处显色效率为25cm2/C的聚苯胺与在570nm处显色效率为206cm2/C的互补显色材料PEDOT进行电化学和光学性能耦合。在- 0.6和1.0V之间切换合适的工作电位窗口，以探索ECD的循环寿命。我们测试了PANI - PEDOT ECD，该ECD由PANI， PEDOT和含有0.1M LiClO4in碳酸丙烯酯和1mM HClO4的有机电解质组成。在570nm处，ECD的透射率从58%（−0.6V）增加到14% (1.0V)，显色效率为285cm2/C。在选定的工作电压范围内，PANI-PEDOT ECD可以循环到2×104cycles。
In this study, two conducting polymers, polyaniline (PANI) and poly(3,4-ethylenedioxythiophene) (PEDOT), were used to construct an electrochromic device (ECD). PANI was employed as the anodic coloring polymer while PEDOT was used as the cathodic coloring polymer. The electrochemical and optical properties of PANI, which has a coloration efficiency of 25cm2/C at 570nm, were coupled with the complementary coloring material, PEDOT, which has a coloration efficiency of 206cm2/C at 570nm. A suitable operating potential window was switched between −0.6 and 1.0V to explore the cycle life of the ECD. We tested the PANI–PEDOT ECD, which consisted of PANI, PEDOT, and an organic electrolyte containing 0.1M LiClO4in propylene carbonate and 1mM HClO4. The transmittance of the ECD at 570nm changed from 58% (−0.6V) to 14% (1.0V) with a coloration efficiency of 285cm2/C. Within the selected operating voltage range, the PANI–PEDOT ECD could be cycled for up to 2×104cycles.
