性质:研究和使用较多的一种杂环共轭型导电高分子,以吡咯为单体,经过电化学氧化聚合制成导电性薄膜,或者用化学聚合方法合成。一种空气稳定性好,易于电化学聚合成膜的导电聚合物,不溶不熔。它在酸性水溶液和多种有机电解液中都能电化学氧化聚合成膜,其电导率和力学强度等性质与电解液阴离子、溶剂、pH值和温度等聚合条件密切相关。导电聚吡咯具有共轭链氧化、对应阴离子掺杂结构,其电导率可达102~103S/cm,拉伸强度可达50~100MPa。及很好的电化学氧化-还原可逆性,可以作为光电化学电池的修饰电极、蓄电池的电极材料。此外,还可以作为电磁屏蔽材料和气体分离膜材料,用于电解电容、电催化、导电聚合物复合材料等,应用范围很广。在聚合物中,吡咯结构单元之间主要以α位相互联接,当在α位有取代基时聚合反应不能进行。用电化学氧化聚合方法可以在电极表面直接生成导电性薄膜,其电导率可以达到102S/cm,且稳定性好于聚乙炔。聚吡咯的氧化电位比其单体低约1V左右,呈黄色,掺杂后呈棕色。聚吡咯也可以用化学掺杂法进行掺杂,掺杂后由于反离子的引入,具有一定离子导电能力。聚吡咯除了作为导电材料使用,如作为特种电极等场合外,还用于电显示材料等方面,作为线性共轭聚合物,聚吡咯还具有一定光导电性质。
