| 摘 要： | 采用化学氧化聚合法以不同浓度的苯胺单体制备聚苯胺(PANI-1和PANI-2),采用相同方法在氮掺杂碳纳米管(NCNTs)悬浮液中制备聚苯胺/氮掺杂碳纳米管复合材料(PANI/NCNTs-1和PANI/NCNTs-2)。利用循环伏安法、恒电流充放电和电化学交流阻抗技术对合成材料的超级电容器性能进行研究分析。在0.2 A/g电流密度下进行恒电流充放电, PANI/NCNTs-1和PANI/NCNTs-2复合材料可以获得较高的比电容。同时, PANI/NCNTs复合材料也具有优异的倍率性能和充放电稳定性,这都表明该复合材料在电化学储能器件领域具有广阔的应用前景。

| Abstract: | Polyaniline (PANI-1 and PANI-2) was prepared via in situ polymerization of aniline monomer in different concentrations.
PANI/nitrogen doped carbon nanotube composites (PANI/NCNTs-1 and PANI/NCNTs-2) were synthesized by the similar route in the
presence of NCNTs suspension. The PANI/NCNTs composites are used as supercapacitor electrodes and the electrochemical performances
are evaluated by cyclic voltammetry, galvanostatic charge/discharge measurement and electrochemical impedance spectroscopy,
respectively. The PANI/NCNTs-1 and PANI/NCNTs-2 composites exhibit better capacitive behavior at a current density of 0.2 A/g.
Furthermore, the composites have good rate capability and stability. The results demonstrate the PANI/NCNTs composites can be used
as promising supercapacitor electrode materials for high performance energy storage devices. |
