Copper phthalocyanine (CuPc) films with different morphologies were electrodeposited on the surfaces of ITO electrodes. Then, in each case, a polyaniline (PANI) film was electrochemically polymerized on the surface of the copper phthalocyanine film to form a CuPc-PANI composite film. The electrochemical properties of the CuPc-PANI composite film were observed to be much better than those of the film without CuPc. With the modification involving the CuPc nanowires, the composite film formed a finer particle surface and an increased interface area between the PANI and the electrolyte. Compared to the single-component PANI film, the CuPc-PANI composite film exhibited better performance with a higher optical contrast (58% at 730 nm), a faster response speed (coloring time of 1.02 s, discoloring time of 1.96 s), and better cycling stability (68.71% of the initial electrochemical activity after 500 cycles, in contrast to only about 48.02% for PANI). Moreover, the CuPc-PANI film shows a new feature that can be used as a supercapacitor (specifically a capacitance value of about 5.4 mF cm at typical currents). Our results demonstrate that the prepared CuPc-PANI composite film is one of the best candidates for multiple potential applications such as high-performance polymer electrochromic materials and supercapacitors.
将具有不同形貌的铜酞菁（CuPc）薄膜电沉积在氧化铟锡（ITO）电极表面。然后，在每种情况下，在铜酞菁薄膜表面通过电化学方法聚合聚苯胺（PANI）薄膜，以形成CuPc-PANI复合薄膜。观察到CuPc-PANI复合薄膜的电化学性能比不含CuPc的薄膜要好得多。通过涉及CuPc纳米线的改性，复合薄膜形成了更精细的颗粒表面以及聚苯胺与电解质之间增加的界面面积。与单组分聚苯胺薄膜相比，CuPc-PANI复合薄膜表现出更好的性能，具有更高的光学对比度（在730 nm处为58%）、更快的响应速度（着色时间为1.02 s，褪色时间为1.96 s）以及更好的循环稳定性（500次循环后初始电化学活性的68.71%，相比之下聚苯胺仅约为48.02%）。此外，CuPc-PANI薄膜显示出一种可作为超级电容器的新特性（在典型电流下电容值约为5.4 mF/cm）。我们的结果表明，所制备的CuPc-PANI复合薄膜是高性能聚合物电致变色材料和超级电容器等多种潜在应用的最佳候选材料之一。
