以单壁碳纳米管（SWNTs）为电极材料，制备了吡咯修饰的超级电容器电极。在6 M KOH中获得了高的电容值（350 F/g）、功率密度（4.8 kW/kg）和能量密度（3.3 kJ/kg），并且电容几乎是对照巴克纸的7倍。这些材料的比电容对大孔表面积有很强的依赖性。基于BET模型，吡咯处理的官能化单壁碳纳米管电极的双电层容量为154 μF/cm 2，并且基于DFT模型甚至更高。
Supercapacitor electrodes based on pyrrole treated-functionalized single wall carbon nanotubes (SWNTs) were developed. High values of capacitance (350 F/g), power density (4.8 kW/kg), and energy density (3.3 kJ/kg) were obtained in 6 M KOH, and the capacitance is almost 7 times that of the control buckypaper. Specific capacitance of these materials has a strong dependence on the macropore surface area. The double layer capacity of pyrrole treated-functionalized SWNT electrodes is 154 μF/cm2 based on the BET model, and even higher based on the DFT model.
