摘要
本文通过元素分析、X射线光电子能谱(xps)、富里哀变换红外光谱(FTIR)及固体^(13)C核磁共振(^(13)C NMR)等测试方法,对化学氧化聚吡咯的导电性及化学结构作了详细探讨。实验结果表明,在氧化态的聚吡咯中,平均每四个吡咯环带有一个负离子(Cl^-),大分子链上的正电荷分布在氮原子上,各吡咯环主要以α-α相连接。经还原剂处理后。聚吡咯的电导率下降了7个数量级,这与大分子链上正电荷的变化有关。
The conductivity and chemical structures of polypyrrole were investigated by means of the analysis of elements, XPS, FTIR, and ^(13)C NMR. It was found that there is an anion (Cl^-) per four pyrrole rings in oxidative polypyrrole, and positive charge is distributed on nitrogen atom and pyrrole rings are a-a' linkage. After treated by reducing agent, the conductivity of polypyrrole decreases by seven orders of magnitude. This is related to the change of positive charge on macromolecule chain.
