摘　　要：将2种二茂铁基表面活性剂(11-二茂铁基)正十一烷基三甲基溴化铵(FTMA)和二(11-二茂铁基)正十一烷基二甲基溴化铵(BFDMA),分别与聚苯乙烯磺酸钠(PSS)进行离子自组装,制备了2种新型的、具有氧化还原活性的复合物PSS-FTMA和PSS-BFDMA,并对制得的PSS-FTMA和PSS-BFDMA进行测试。研究结果表明,复合物处于介晶态,修饰电极的电化学行为都受扩散控制的准可逆过程,PSS-FTMA的电极反应速率为0.69,比PSSBFDMA电极反应速率0.13要高4.3倍,PSS-FTMA具有较好的电化学性能。Two new and redox active complexes PSS-FTMA and PSS-BFDMA were'prepared via ionic self-assembly of sodium poly(styrenesulfonate)(PSS)and two ferrocenyl surfactant,FTMA and BFDMA,and the prepared samples were tested and analyzed.The research results indicated that the complexes exhibited mesomorphous structures,The electrochemical behavior of modified electrode was a quasi reversible process controlled by diffusion. The electrode reaction rate of PSS-FTMA was 0.69,which was 4.3 times higher than that of PSS-BFDMA.PSS-FTMA had better electrochemical performance.
