摘　　要：采用界面聚合法,以大分子掺杂酸樟脑磺酸为掺杂剂,合成了苯胺/邻甲苯胺共聚物。利用红外光谱(FT-IR)和紫外光谱(UV-vis),对该共聚物成分和结构进行了表征。通过循环伏安和恒流充放电技术考察了该共聚物的电化学电容行为。结果表明,制备的活性电极材料樟脑磺酸掺杂苯胺/邻甲苯胺共聚物在1mol/LH2SO4溶液中呈现一定的电化学电容行为。随着扫速从3mV/s增大到10mV/s,峰电流从5mA增大11mA,表明该聚合物具有较快的电流响应。在电流密度为1.5mA/cm2时,单电极比电容达到275F/g,表明该材料在电化学电容器中有一定的应用前景。Poly（aniline-co-o-toluidine） doped with big molecular dopant acid,camphorsulfonic acid （CSA）,was prepared by interfacial polymerization. The component and structure of the polymer were characterized by Fourier transform infrared spectrum（FT-IR） spectra and UV-vis spectra. The electrochemical capacitance performance of the polymer as electrochemical active material was investigated by cyclic voltammetry and galvanostatic discharge techniques. The results demonstrate that the as-prepared poly（aniline-co-o-toluidine） exhibits electrochemical capacitive behavior in 1 mol/L H2SO4 solution. With the increase of the scan rate,the peak current increases from 5 mA to 11 mA,showing quick current response. Its specific capacitance as single electrode is up to 275 F/g at a current density of 1.5 mA/cm2,indicative of potential application for electrochemical capacitors.
