The effects of experimental conditions on the fractal structure of electrosynthetic polyparaphenylene
films were studied by electrochemical impedance spectroscopy. The results indicate that, at the potential
range (0-0.6 V), the film surface fractal dimension rises while the corresponding charge transfer resistances
Rct decrease as charge increases. This is consistent with the oxidized behavior of the conducting
polymer. As for the degradation of electrolytes, scanning electron microscopy observations of poly(parapheneylene)
(PPP) film provide evidence of the close relationship between the degradation of electrolytes
and the film morphology, also in good agreement with the electrochemical impedance results interpretation.
The X-ray photoelectron spectroscopic analysis results present that the relative oxygen content ratio
(O/C) of the films increases with the times the electrolyte is used, which reveals that the degradation of the
electrolyte may result in a compact and passivation PPP film. - 英文摘要: --
