A difunctional porous network of poly(indole-6-carboxylicacid) (PICA)/TiO nanocomposites is first prepared using TiO nanorod arrays as the scaffold. Because of the synergistic effect of PICA and TiO, the nanocomposites show good electrochemical performance, a high specific capacitance value (23.34 mF cm), and excellent galvanostatic charge-discharge stability. Meanwhile, this nanocomposite can be reversibly switched (yellow, green, brown) with a high coloration efficiency (124 cm C). An asymmetric electrochromic-supercapacitor device (ESD) is also constructed using the PICA/TiO nanocomposites as the anode material and poly(3,4-ethylenedioxythiophene) as the cathode material. This ESD has robust cycle stability and a high specific capacitance value (9.65 mF cm), which can be switched from light green to dark blue. After charging, the device can light up a single LED for 108 s, and the energy storage level can also be monitored by the corresponding color changes. This constructed ESD will have great potential applications in intelligent energy storage and other smart electronic fields.
首次使用 TiO 纳米棒阵列作为支架制备了聚（吲哚-6-羧酸）（PICA）/TiO 纳米复合材料的双功能多孔网络。由于 PICA 和 TiO 的协同作用，纳米复合材料表现出良好的电化学性能，具有高比电容值（23.34 mF cm）和优异的恒电流充放电稳定性。同时，该纳米复合材料可以通过高着色效率（124 cm C）可逆地切换（黄色、绿色、棕色）。还使用 PICA/TiO 纳米复合材料作为阳极材料和聚（3,4-乙撑二氧噻吩）作为阴极材料构建了非对称电致变色超级电容器装置（ESD）。该 ESD 具有稳健的循环稳定性和高比电容值（9.65 mF cm），可以从浅绿色变为深蓝色。充电后，该装置可以点亮单个 LED 108 s，并且可以通过相应的颜色变化来监测储能水平。所构建的 ESD 将在智能储能和其他智能电子领域具有巨大的应用潜力。
