| 摘 要： | 以(NH4)2S2O8为氧化剂,在1 mol/L盐酸环境下化学氧化合成超级电容器用电极材料纳米聚苯胺(PANI)。在1 mol/L H2SO4溶液中考察了材料的电容性能。结果表明:在循环伏安图上出现三对氧化还原峰,分别对应聚苯胺在三种不同氧化状态间的转化以及PANI的降解。放电电流密度为(1.0,4.5,10)×10–3A/cm2时,比容量分别为654,591,525 F/g。经恒定电流10 mA充放电循环1 000次,衰减仅为初始容量的10.7%。

| Abstract: | Polyaniline nanoparticles was synthesized in 1 mol/L HCl solution using(NH4)2S2O8 as oxidant under protection of N2.Investigated was the capacitance performance of polyaniline in 1 mol/L H2SO4 aqueous solution.The results show that three redox peak are observed from voltammogram in the potential range of 0～0.7 V(vs Ag/AgCl),indicating the transitions of polyaniline bentween different oxidation states and its degradation.Specific capacitance of 654 F/g is obtained at current density of 1.0×10–3 A/cm2,comparing with that of 591 F/g and 525 F/g at 4.5×10–3 A/cm2,10×10–3 A/cm2,respectively.After 1 000 cycles of charge/discharge at constant current density of 10×10–3A/cm2,specific capacitance is decreased only 10.7 %. |
