摘要
采用循环伏安法制备了苯胺(AN)/对氨基苯磺酸(4-ABSA)共聚物修饰电极,并测试了其在Na2SO4中性溶液中的电化学性能。探讨了AN与4-ABSA的摩尔比、聚合扫速等因素对共聚物电化学性能的影响。结果表明:4-ABSA单体含量越高,共聚越难;当AN与4-ABSA的摩尔比为1:1时所得共聚物在中性溶液中表现出良好的电化学活性;聚合扫速对共聚物的电化学性能没有明显的影响。
Aniline （AN） / 4-aminobenzenesulfonic acid （4-ABSA） copolymers-modified electrodes were prepared by cyclic voltammetry, followed by investigations on their electrochemical performance in Na2SO4 neutral solution. The influences of AN/4-ABSA mole ratio and scan rate of polymerization on the electrochemical performances of the copolymers were analyzed. The results indicate that the higher content of 4-ABSA makes copolymerization harder. When the mole ratio of AN to 4-ABSA is 1：1, the prepared copolymer shows a better electrochemical activity in the neutral solution. The scan rate of polymerization has little influence upon the electrochemical performance.
