摘要
采用脉冲电沉积法制备得到纤维状聚苯胺,采用X射线衍射(XRD)、扫描电镜(SEM)及红外光谱(FT-IR)等手段对其结构、形貌等进行了表征。将所得聚苯胺用作超级电容器电极材料,采用恒流充放电、循环伏安(CV)和电化学阻抗(EIS)等技术测试其电化学性能,1.0A·g-1下的放电比容量为336.3F·g-1。
Fibre like polyaniline was synthesized by pulse electrodeposition. The morphology and micro-structure of polyaniline were investigated by X-ray diffraction （XRD）, scanning electron microscopy （SEM） and Fouri- er transfer infrared spectroscopy （FT-IR）. The as-prepared polyaniline was used as supercapacitor electrode. And the electrochemical performance was evaluated by galvanostatic charge-discharge, cyclic voltammetry （CV） and electeochemical impedance spectra（EIS）. The specific capacitance of polyaniline was 336.3F· g^-1 at a current density of 1A·g^-1.
