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。 In this paper, the electrochemical oxidation of polypyrrole was investigated by elemental analysis, x-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and 13C nuclear magnetic resonance (~ Sexual and chemical structure were discussed in detail. The experimental results show that, in the polypyrrole oxidation state, an average of four anions (Cl ~ -) exist on each pyrrole ring, the positive charge on the macromolecular chain is distributed on the nitrogen atom, and each pyrrole ring mainly takes the α-α phase connection. After the reductant treatment. Conductivity of polypyrrole decreased by seven orders of magnitude, which is related to the change of positive charge on the macromolecular chain.
