With the increasing focus on energy crisis and environmental protection, polypyrrole/muti walls carbon nanotubes (PPy/MWCNTs) composites which possess relatively high specific capacitance are a class of promising electrode active material for energy storage devices. This study proposes a method using two dopants, copper phthalocyanine-3,4′,4″,4‴-tetrasulfonic acid tetrasodium salt (CuPcTs) and phytic acid (PA), for adjusting the porous nanostructure and improving the electrochemical performance of PPy/MWCNTs electrodes. Compared with the particle-like PPy/MWCNTs and PA-PPY/MWCNTs (p-PPy/MWCNTs) electrodes, the 3D fiber-like CuPcTs-PPy/MWCNTs (c-PPy/MWCNTs) electrodes with a smaller diameter and higher specific surface area can provide more electron successive pathways and ion diffusion tunnels and active sites. The c-PPy/MWCNTs electrodes exhibit the highest specific capacitance of 488 F g⁻¹ @ 5 A g⁻¹ and 451 F g⁻¹ @ 10 mV s⁻¹, which is approximately 2 and 1.6 times of p-PPy/MWCNTs and PPy/MWNCTs with the specific capacitance of 265 F g⁻¹ @ 5 A g⁻¹and 246 F g⁻¹@ 5 A g⁻¹ and 288 F g⁻¹ @ 10 mV s⁻¹ and 267 F g⁻¹ @ 10 mV s⁻¹, respectively. The PPy/MWCNTs doping with CuPcTs can be used as an excellent electrode for the fabrication of energy storage devices and affords a modifying method for other active materials.

随着对能源危机和环境保护的日益关注，具有相对高的比电容的聚吡咯/多壁碳纳米管（PPy / MWCNT）复合材料是一类有前景的储能器件电极活性材料。这项研究提出了一种使用两种掺杂物的方法，即铜酞菁铜3,4'，4''，4‴-四磺酸四钠盐（CuPcTs）和植酸（PA），用于调节多孔纳米结构并改善PPy / MWCNTs电极。与颗粒状PPy / MWCNTs和PA-PPY / MWCNTs（p-PPy / MWCNTs）电极相比，直径较小，比表面积更高的3D纤维状CuPcTs-PPy / MWCNTs（c-PPy / MWCNTs）电极区域可以提供更多的电子连续路径，离子扩散隧道和活性位点。^-1 @ 5 A g ^-1和451 F g ^-1 @ 10 mV s ^-1，约为p-PPy / MWCNTs和PPy / MWNCT的2倍和1.6倍，比电容为265 F g ^-1 @ 5 A g ^-1和246 F g ^-1 @ 5 m g ^-1和288 F g ^-1 @ 10 mV s ^-1和267 F g ^-1 @ 10 mV s ^-1。掺杂有CuPcTs的PPy / MWCNTs可以用作制造能量存储设备的极好电极，并为其他活性材料提供改性方法。
