件，在当今社会具有重要的研究价值和应用意义。鉴于此，本工作通过控制单质吡咯（Py）和氧化剂过硫酸铵（APS）的比例制备出具有高性能的球形颗粒聚吡咯（PPy）电极材料；利用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）等对电极材料的微观形貌结构进行表征；同时利用电化学工作站对电极电化学性能进行分析。结果表明，当Py与APS的摩尔比为1∶1时，表现出优异的电化学性能，在0.3 A/g的电流密度下表现出193.5 F/g的高比电容，5 A/g电流密度下经过5000次充放电循环后，仍有85%的电容保持率。此外，配制具有优异流变性能的丝网印刷油墨，基于丝网印刷工艺组装柔性叉指超级电容器，对比普通叉指器件，齿形叉指器件表现出更为优异的电化学性能，在1 mA/cm

的电流密度下经过5000次充放电循环后，电容保持率高达91%，当功率密度为0.11 mW/cm

时，可产生0.0344 mWh/cm

的能量密度。因此，本工作制备了PPy油墨，通过丝网印刷工艺组装柔性齿形叉指超级电容器，其在柔性电子设备储能领域具有广阔的发展前景。

Abstract

The search for electrode materials with high capacitance performance for use in flexible energy storage devices is of significant research and application importance in contemporary applications. Herein

high-performance spherical polypyrrole (PPy) electrode materials were prepared by controlling the ratio of pyrrole (Py) and the oxidant ammonium persulfate (APS). The microstructure of the electrode materials was characterized using scanning electron microscopy

transmission electron microscopy

X-ray diffraction

and Fourier transform infrared spectroscopy

while the electrochemical performance of the electrode was analyzed using an electrochemical workstation. The results show that when a Py-to-APS molar ratio of 1∶1 yields excellent electrochemical performance

with a high specific capacitance of 193.5 F/g at a current density of 0.3 A/g

and a capacitance retention rate of 85% after 5000 charge–discharge cycles at a current density of 5 A/g. In addition

an ink with excellent rheological properties was formulated

and a flexible interdigital supercapacitor was fabricated via a screen-printing process. Compared with conventional interdigital devices

toothed interdigital designs exhibit superior electrochemical performance. The resulting device shows a capacitance retention rate of up to 91% after 5000 charge-discharge cycles at an area current density of 1 mA/cm

. At a power density of 0.11 mW/cm

t delivers an energy density of 0.0344 mWh/cm

. Overall

the PPy ink developed in this study

combined with the fabrication of a flexible toothed interdigital supercapacitor through screen printing

demonstrates promising potential for applications in flexible electronic energy storage devices.
