| 摘 要： | 采用循环伏安一步共聚法在碳纳米管修饰的铂基体上制备了电活性碳纳米管/聚苯胺/铁氰化镍(CNTs/PANI/NiHCF)复合膜.用傅立叶变换红外(FT-IR)光谱、X射线能谱仪(EDS)和扫描电镜(SEM)研究了复合膜组成及其表面形貌,并用循环伏安(CV)、恒电流充放电和电化学阻抗(EIS)等测试了复合膜的循环稳定性与电化学容量性能.研究表明:CNTs/PANI/NiHCF复合膜为三维多孔有序的网络状结构,PANI和NiHCF以纳米颗粒形式存在并沿CNTs均匀分布;在电流密度为2mA.cm-2时,CNTs/PANI/NiHCF复合膜的比容量高达262.28F.g-1,比能量为29.51Wh.kg-1,电流密度为10mA.cm-2时比功率可达10228.61W.kg-1;在2000次循环充放电过程中,复合膜的电容量仅衰减19.92%,电荷充放电效率一直保持在99%以上.CNTs/PANI/NiHCF有机-无机杂化膜具有良好的功率特性和快速充放电能力,是一种优异的超级电容器材料.

| Abstract: | Electroactive composite films of carbon nanotubes/polyaniline/nickel hexacyanoferrate (CNTs/PANI/ NiHCF) were synthesized on platinum substrates modified with CNTs by a one-step co-polymerization using cyclic voltammetry. The composite films were characterized by Fourier transform infrared spectroscopy (FT-IR),energy dispersive X-ray spectroscopy (EDS),and scanning electron microscopy (SEM). Cyclic voltammetry (CV),galvanostatic charge/ discharge,and electrochemical impedance spectroscope (EIS) methods were... |
