Abstract
In this work, the in-situ viscoelastic characteristics of electro-polymerized polypyrrole (Ppy) thin film were investigated in the electrolyte solution of KClO4, LiClO4 and NaClO4 using quartz crystal analyzer (QCA). One side of quartz crystal electrode was used as a working electrode mounted in a specially fabricated QCA electrochemical cell. The resonant frequency and resistance diagram was utilized to interpret the viscoelastic behavior of Ppy thin film. The larger the size of cation is, the more distinct the viscoelastic change is due to the cation penetration into the polypyrrole thin film. The cyclic voltammetry, using Ppy deposited AT-cut quartz crystal electrode, suggests that the swelling of Ppy film reduces the conductivity of the Ppy film.
