考察了多扫循环伏安法制备出的聚十二烷基苯磺酸/聚苯胺(PDBSA/PANI)复合材料的电化学性能。结果表明,与自吸附十二烷基苯磺酸/聚苯胺(DBSA/PANI)、纯PANI相比,PDBSA/PANI复合材料的荷电量最大,电化学阻抗最小,说明PDBSA更能显著地增强PANI的导电性;PDBSA/PANI复合材料的比电容为407.692F/g,比DBSA/PANI复合材料(339.307F/g)和纯PANI(235.088F/g)均高,表明PDBSA可以较大程度地改善PANI的电荷贮存性;pH和扫速试验显示PDBSA没有改变PANI的单电子单质子的氧化还原反应,说明PDBSA没有参与到聚苯胺的氧化还原反应中。
The electrochemical properties of the polydodecyl phenylsulfonic acid/polyaniline (PDBSA/PANI) composite material prepared by multiple sweep cycle voltammetry were investigated.The results showed that,compared with self-adsorbed DBSA/PANI and pure PANI,the PDBSA/PANI composite had the largest charge and the smallest electrochemical impedance,indicating that polydodecyl phenysulfonic acid could significantly enhance the conductivity of polyaniline.The specific capacitance of the PDBSA/PANI composite was 407.692F/g,which was higher than that of DBSA/PANI composite (339.307F/g) and pure PANI (235.088F/g),indicating that the PDBSA could greatly improve the charge storage of the PANI.PH and sweep test revealed that PDBSA did not change the redox reaction of PANI,indicating that PDBSA was not involved in the redox reaction of PANI.
