摘要
研究了低电流密度下恒电流法制备的聚苯胺（ＰＡ）修饰电极的性质及其影响因素，探讨了低电流密度聚合的ＰＡ膜的优点。发现此种条件下聚合的ＰＡ膜具有较好的电荷传输能力，它不仅对Ｂｒ￣－、Ｔｌ￣＋／Ｔｌ等电对的氧化还原反应有更好的电催化活性，而且对Ｈ￣＋的Ｎｅｒｎｓｔ响应也更接近理论值。
The properties of polyaniline modified electrodes prepared by galvanostatic at low current density were studied.Advantages of the polymer-coated electrodes prepared at these conditions were also discussed.It was found that polyaniline film polymerized at low current density had good electron transfer. Not only have it a better ability of electrocatalysis to the redox reaction of Br￣- and Tl￣+/Tl, but also it has a good response to H￣+.
