聚苯胺（PANI）和聚（3-己基噻吩）（P3HT）是具有电致变色特性的导电聚合物。在这项工作中，两种聚合物都在单电致变色器件（ECD）中进行了研究。PANI和P3HT是互补的电致变色聚合物，在双重器件的氧化还原过程中，这两张膜同时被澄清和遮盖。这种颜色变化在双ECD中提供了明显的透光率差异。两种聚合物均通过化学方法合成。研究了P3HT薄膜在单次和两次ECD中沉积方法的影响。在ECD中使用了聚甲基丙烯酸甲酯和高氯酸锂溶解在乙烯和碳酸亚丙酯中的粘性聚合物电解质（PE）。单设备和双设备的体系结构设计分别是GLASS / ITO / PANI或P3HT / PE / ITO / GLASS和GLASS / ITO / PANI / PE / P3HT / ITO / GLASS。电致变色器件是在环境条件下构造的。获得了彩色和漂白态的透射光谱，以及单和双ECD在550 nm处的动力学光学透射率曲线。与单个设备相比，基于P3HT-PANI的双ECD表现出更快的透射率变化率，更高的稳定性和更高的透射率变化。透射率的差异取决于薄膜的沉积技术。在550nm处获得57％的光学对比度。获得了单和双ECD在550 nm处的动力学透光率曲线。与单个设备相比，基于P3HT-PANI的双ECD表现出更快的透射率变化率，更高的稳定性和更高的透射率变化。透射率的差异取决于薄膜的沉积技术。在550nm处获得57％的光学对比度。获得了单和双ECD在550 nm处的动力学透光率曲线。与单个设备相比，基于P3HT-PANI的双ECD表现出更快的透射率变化率，更高的稳定性和更高的透射率变化。透射率的差异取决于薄膜的沉积技术。在550nm处获得57％的光学对比度。

Study of dual electrochromic devices based on polyaniline and poly (3-hexylthiophene) thin films

Polyaniline (PANI) and poly (3-hexylthiophene) (P3HT) are conducting polymers exhibiting electrochromic properties. In this work both polymers were studied in single and dual electrochromic devices (ECDs). PANI and P3HT are complementary electrochromic polymers, both films in its redox process in a dual device are clarified and obscured at the same time. This color change provided a significant difference in optical transmittance in a dual ECD. Both polymers were synthesized by chemical method. The effect of deposit method of P3HT films in the single and dual ECDs was studied. A viscous polymeric electrolyte (PE) of polymethyl methacrylate and lithium perchlorate dissolved in ethylene and propylene carbonates was used in ECDs. The architectural design of single and dual device was GLASS/ITO/PANI or P3HT/PE/ITO/GLASS and GLASS/ITO/PANI/PE/P3HT/ITO/GLASS, respectively. The electrochromic devices were constructed under environmental conditions. Transmittance spectra of colored and bleached states, and kinetic optical transmittance curves at 550 nm of single and dual ECDs were obtained. Dual P3HT-PANI-based ECDs exhibited a faster rate of transmittance change, higher stability and higher transmittance change compared with the single devices. The difference in transmittance depended of the deposit technique of the films. An optical contrast of 57 % was obtained at 550 nm.
