摘　　要：以邻联甲苯胺和均苯三甲醛为反应单体,通过一种简单的席夫碱反应一步合成了席夫碱导电聚合物(TBOT),同时在席夫碱导电聚合物合成过程中掺杂不同摩尔比的二茂铁,制备了席夫碱-二茂铁复合电极材料(TBOT-Fc),采用循环伏安法(CV)、恒流充放电法(GCD)和电化学阻抗谱法(EIS)测试了所制备的复合材料电化学性能。结果表明,TBOT-Fc_(0.5)的电化学性能明显优于TBOT,特别是在0.5 A/g电流密度时,比电容达到153.1 mAh/g,此外所构建的非对称超级电池设备TBOFc_(0.5)//AC,在电流密度为0.5 A/g时功率密度为334.8 W/kg,能量密度达到了优异的46.5 Wh/kg。Schiff base conductive polymers(TBOT)via a one-step Schiff-base reaction have synthesized by using o-toluidine and homobenzotrialdehyde as reaction monomers.The Schiff-base ferrocene composite electrode material(TBOT-Fc)was also prepared by doping different proportions of ferrocene during the synthesis of Schiff-base conducting polymer.The electrochemical properties of the prepared composites were tested by cyclic voltammetry(CV),constant current charge-discharge(GCD)and electrochemical impedance spectroscopy(EIS).The results revealed that the electrochemical performance of TBOT-Fc_(0.5) was significantly higher than that of TBOT,especially the specific capacitance reached 153.1 mAh/g at the current density of 0.5 A/g.In addition,the constructed asymmetric supercapattery device(TBOFc_(0.5)//AC)had a power density of 334.8 W/kg and an energy density of 46.5 Wh/kg at a current density of 0.5 A/g.
