以对甲基苯磺酸(TSA)为掺杂剂和乳化剂,过硫酸铵(APS)为引发剂,采用现场乳液聚合方法合成了对甲基苯磺酸掺杂聚(苯胺/中性红)复合材料(TSA-PANI/PNR).利用X射线衍射(XRD)和电子扫描显微镜(SEM)对共聚物复合材料的结构和形貌进行了分析和表征.以此复合材料为活性物质制备电极,以l mol/L H_2SO_4水溶液为电解液组装超级电容器,通过恒电流充放电、循环伏安和交流阻抗等技术研究了其电化学性能.研究结果表明,TSA-PANI/PNR电极具有比TSA/PANI更优良的电化学性能.扫描速度为1 mV/s的循环伏安曲线计算结果表明,其单电极比电容可达到1350 F/g,而TSA/PANI在相同的扫速下其单电极比电容仅为1038 F/g;在5 mA放电电流下,TSA-PANI/PNR组装的电容器首次充放电比电容可达到348 F/g,1000次循环后容量保持87%.

Using paratoluenesulfonic acid(TSA) as dopant and emulsifier, and ammonium persulfate(APS) as initiator, the composites of polyaniline, TSA and neutral red(TSA-PANI/PNR) were synthesized by emulsion polymerization. The structure and morphology of the composites were investigated by X-ray diffraction(XRD) and scanning electron microscopy(SEM). Symmetric redox supercapacitor was assembled with TSA-PANI/PNR as active electrode material and an l mol/L H_2SO_4 aqueous solution as electrolyte. The electrochemical performances of the supercapacitors were characterized by galvanostatic charge-discharge, cyclic voltammetry and A.C. impedance spectroscopy. The results show that TSA-PANI/PNR composite exhibits outstanding electrochemical capacitor performance compared with TSA/PANI electrode. The specific capacitance measured from cyclic voltammetry is 1350 F/g for TSA-PANI/PNR composite material and 1038 F/g for TSA/PANI at 1 mV/s scan rate;the initial specific capacitance of the TSA-PANI/PNR supercapacitor is about 348 F/g at a constant current of 5 mA. Meanwhile, the retention of the capacitance after 1000 charge-discharge cycles was 87%.
