摘要: 丁基噻吩在硝基苯溶液中以六氟磷酸四丁基季铵盐为支持电解质,在恒电流条件下进行电化学氧化聚合,通过电导率的测量及可见──紫外光谱分析,讨论了单体浓度、电解质浓度、电流密度、聚合温度对聚合物膜的导电性能的影响。扫描电镜图表明,随着聚合的进行.膜的表面呈“菜花”状结构。循环伏安图表明聚了基噻吩与聚噻吩具有相近的氧化峰位。Abstract: Electrochenical polymerization of 3-butylthiophene was carried out under galvanostatic conditions in a nitrobenzen solution containing tetrabutylammonium hexafluorophosphate as a suppoiting electrolyte.
