Abstract :
The in-situ viscoelastic and opto-chemical behaviors of the PolyPyrrole (PPy) thin film were investigated using quartz crystal coupled with QCA917 and ultraviolet/visible light cell. Using galvanostatical method, PPy films were deposited onto the electrode of quartz crystal at various deposition conditions. The dynamic property changes of deposited PPy film were analyzed in the cyclic voltametric experiment using PPy deposited quartz crystal as working electrode. The resonant frequency and resonant resistance as well as the transmittance change of PPy films were measured and the redox property was analyzed simultaneously
