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。

Abstract: 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+.
