- 中文摘要: Cyclic voltammograms and morphology of polyaniline were studied under various synthetic conditions and in various protonic acid media. The effect of protonic acid is not remarkable. The cyclic voltammogram and morphology depend on the synthetic conditions. The anodic peak potential at 0.14V versus SCE in the cyclic voltammogram is pH independent. The anodic peak potential at 0.7 V versus SCE(pH=1) is pH dependent. By comparing the range of pH and oxidation potential of the conductive form , we propose that conductive species which exists in the potential range between the first and the second peak in cyclic voltammogram is the radical cation.
