摘要： 对聚苯胺在有机溶剂中掺杂质子酸的反应进行了in-situ UV-Vis光谱跟踪,用因子分析法对掺杂反应机理进行了研究.结果表明,聚苯胺在有机溶剂中掺杂质子酸的过程可能存在着两个并行反应:一个是掺杂与脱掺杂的动态平衡过程,在实验条件下反应的平衡常数约为k=5.16(24℃);另一个反应为副反应,生成的产物结构介于本征态与平衡掺杂态之间,很可能是反应过程中形成的包含不同掺杂形态的混合体.

Abstract: In situ UV-Vis spectra for protonic acid doping reaction of polyaniline in organic solvent were recorded. The doping reaction mechanism was obtained from the chemical factor analysis for the first time. The results show that two competing reactions might exist during the doping process: one is the dynamic equilibrium between doping and dedoping reaction, and the equilibrium constant being k = 5.16(24 ℃); the other is a side reaction. The product of the side reaction should be a doped mixture between intrinsical and doped states formed during the reaction.

Key words: Polyaniline, Doping, In-situ UV-Vis spectrum, Factor analysis
