In this work polypyrrole nanoparticles of high electrochemical activity were used to prepare disposable, potentiometric sensors with a paper support. The paper support modified with polypyrrole nanoparticles served as electrical lead and ion-to-electron transducer and it was covered by a typical poly(vinyl chloride) based ion-selective membrane. The properties of this arrangement were tested on example of potassium-selective electrodes. The sensors prepared benefited from the properties of conducting polymer nanostructures: high electrical conductivity and electroactivity as well as absence of suspension stabilizing agent. The obtained electrodes were characterized with analytical parameters well comparable with those of classical ion-selective electrodes.

基于聚吡咯纳米颗粒的一次性电位传感器

在这项工作中，具有高电化学活性的聚吡咯纳米粒子被用于制备带有纸支撑的一次性电位传感器。用聚吡咯纳米粒子改性的纸载体用作电引线和离子-电子转换器，它被典型的聚（氯乙烯）基离子选择性膜覆盖。这种排列的特性在钾选择性电极的例子上进行了测试。制备的传感器受益于导电聚合物纳米结构的特性：高导电性和电活性以及不存在悬浮稳定剂。所得电极的分析参数与经典离子选择性电极的分析参数相当。
