摘　　要：利用聚苯胺和普鲁士蓝的协同作用,构建了聚苯胺-普鲁士蓝/普鲁士蓝复合膜的H_(2)O_(2)电化学传感器。聚苯胺的带正电骨架和带负电的普鲁士蓝粒子相互吸引,且聚苯胺提供了很多氧化还原位点,有利于普鲁士蓝粒子的进一步均匀生长,使制备的传感器具备优异的电催化性能。采用扫描电镜和电化学方法对修饰电极进行了表征。在最佳实验条件下,该修饰电极不仅表面具有致密均匀的结构,而且具备在弱碱性条件下良好的电化学操作稳定性,为搭建以H_(2)O_(2)传感为基础的新型传感器提供了一个新的思路。Using the synergistic effect of polyaniline and Prussian blue, a hydrogen peroxide electrochemical sensor with polyaniline-Prussian blue/Prussian blue composite membrane was constructed. The positive charged framework of polyaniline and the negatively charged Prussian blue particles attract to each other.The polyaniline provides many redox sites, which is conducive to the further uniform growth of Prussian blue particles, so that the prepared sensor has excellent electrocatalytic performance. The modified electrode was characterized by scanning electron microscopy and electrochemical method. The results showed that under the optimal experimental conditions, the modified electrode not only has a compact and uniform structure on the surface, but also has good electrochemical operation stability under weak alkaline conditions, which provides a new idea for the construction of a new sensor based on hydrogen peroxide sensing.
