PSS stands out as a leading commercial conducting polymer due to its excellent water dispersibility, controllable miscibility, adjustable conductivity, and ability to form films through various techniques. This study investigates the electrochemical and electrochromic performance of electrodes prepared by depositing PEDOT:PSS onto ITO surfaces by using two distinct methods: conventional spray coating and electrospray deposition. Detailed characterization of the prepared electrodes was performed by using atomic force microscopy, scanning electron microscopy, Fourier-transform infrared, and Raman spectroscopy techniques. Our findings reveal that electrodes fabricated via electrospray deposition (PEDOT:PSS/ITO electrode_2) significantly outperform those made by spray coating (PEDOT:PSS/ITO electrode_1). Specifically, electrode_2 exhibits a capacitance of 1678.60 μF cm, compared to 826.14 μF cm for electrode_1, at a current density of 10 μA cm.
PSS electrodes exhibit areal energy densities of 0.41 and 0.84 mW h cm, along with power densities of 4.96 and 4.97 μW cm, respectively. Moreover, electrode_2 demonstrates a high coloration efficiency of 84.32 cm C and fast response times of 1.36 s for coloration and 0.98 s for bleaching. This study highlights the advantages of electrospray deposition over traditional methods, showcasing the potential of electrospray-prepared PEDOT:PSS electrodes for use in multifunctional energy storage devices.
聚（3,4-乙撑二氧噻吩）：聚苯乙烯磺酸钠（PEDOT:PSS）因其出色的水分散性、可控的混溶性、可调节的导电性以及通过各种技术形成薄膜的能力，成为一种领先的商业导电聚合物。本研究通过两种不同方法将PEDOT:PSS沉积到氧化铟锡（ITO）表面来制备电极，从而研究其电化学和电致变色性能：传统喷涂和电喷雾沉积。通过原子力显微镜、扫描电子显微镜、傅里叶变换红外光谱和拉曼光谱技术对制备的电极进行详细表征。我们的研究结果表明，通过电喷雾沉积制备的电极（PEDOT:PSS/ITO电极_2）明显优于通过喷涂制备的电极（PEDOT:PSS/ITO电极_1）。具体而言，在电流密度为10 μA/cm²时，电极_2的电容为1678.60 μF/cm²，而电极_1为826.14 μF/cm²。
PSS电极的面积能量密度分别为0.41和0.84 mW h/cm²，功率密度分别为4.96和4.97 μW/cm²。此外，电极_2表现出84.32 cm²/C的高着色效率，着色响应时间为1.36 s，漂白响应时间为0.98 s。本研究突出了电喷雾沉积相对于传统方法的优势，展示了电喷雾制备的PEDOT:PSS电极在多功能储能设备中的应用潜力。
