聚吡咯(PPy)是广泛使用的高导电性和高稳定性杂环聚合物，主要用于电化学应用。它具有稳定氧化性和高水溶性，是高性价比的导电聚合物。与聚苯胺相比柔性更高，材料密度支持更高的比电容量。
聚吡咯可通过标准的电化学技术制备而成，还可通过水介质中的-萘磺酸(NSA)和过硫酸铵反应制备而成。在合成中掺杂这种聚合物，可轻松改变表面电荷。掺杂樟脑磺酸和十二烷基苯磺酸的聚吡咯的溶解性和电导率测量已有报道。聚吡咯的电敏感性和低氧化电位使其在药物递送、化学传感器、电池、离子选择性电极、生物传感器和生物化学研究中具备潜在应用前景。

應用

可用作热塑性塑料和热固性塑料的导电添加剂。聚丙烯复合材料构成了聚合物电解质膜燃料电池 (PEMFC)。在聚丙烯复合材料中加入聚吡咯会改变其导电性。
聚吡咯主要用于制备各种电化学装置，包括超级电容、化学传感器、染料敏化太阳能电池和锂离子电池。
聚吡咯可用于各种应用，如：
  • 心电图(ECG)用传感器的电极材料
  • 储能应用电极材料
  • 包覆硫化锂(Li2S)制备高性能阴极材料

导电聚合物。
