In this study, polypyrrole nanofiber (PPyNF)/NiO composites were synthesized by a simple and fast microwave method. The samples were characterized using differential scanning calorimetry and thermal gravimetric analysis (DSC/TGA), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Furthermore, the synthesized PPyNF/NiO nanocomposites were electrochemically characterized using galvanostatic charge-discharge, cyclic voltammetry and electrochemical impedance spectroscopy (EIS) techniques. They showed the highest specific capacitance of 657 F g at 0.5 A g, demonstrating their potential application in supercapacitors.
在本研究中，通过一种简单快速的微波方法合成了聚吡咯纳米纤维（PPyNF）/NiO复合材料。使用差示扫描量热法和热重分析（DSC/TGA）、X射线光电子能谱（XPS）和扫描电子显微镜（SEM）对样品进行了表征。此外，使用恒电流充放电、循环伏安法和电化学阻抗谱（EIS）技术对合成的PPyNF/NiO纳米复合材料进行了电化学表征。它们在0.5 A g时显示出最高比电容为657 F g，表明其在超级电容器中的潜在应用。
