摘要
以盐酸为掺杂剂,苯胺为单体,过硫酸钾为引发剂,用MnO_2作添加剂,以水溶液聚合法制备了导电聚苯胺/MnO_2复合电极材料。将所制备的材料制作成超级电容器用的电极片,通过对电极材料进行CV测试、阻抗测试及超级电容器充放电测试,探讨了MnO_2添加量对聚苯胺/MnO_2复合电极的电化学性能影响。结果表明,当苯胺用量为0.3 mol时,MnO_2添加量为1.5 g时所制备的聚苯胺/MnO_2复合电极材料具有最佳的电化学性能。基于该电极片的超级电容器比电容高达408 F·g^(-1)。
PANI/MnO2 composites were prepared by aqueous solution polymerization with HCl as the dopant,aniline as the monomer,K_2S_2O_8 as the initiator and MnO2 as the additive. The PANI/MnO2 composites were used to prepared electrodes of supercapacitor. The effect of MnO2 dosage on the electrochemical properties of PANI/MnO2 composites electrode were investigated by cyclic voltammetry,EIS and charge-discharge test. The results showed that the PANI/MnO2 composites electrode had the best electrochemical performance when the MnO2 dosage was 1. 5 g. Based on the PANI/MnO2 electrode,the specific capacitance of the supercapacitor reached up to 408 F·g^-1.
