Abstract
In situ electrochemical quartz crystal oscillator method was applied to aqueous acid electrolyte solutions of aniline to investigate changes in viscoelasticity of polyaniline during electrochemical growth. Changes in both resonant frequency and resonant admittance were in the order H2SO4 > HNO3 > HBr > HCl > HClO4 ≥ H3PO4 ≥CF3COOH Thus decreases in resonant frequency during electrochemical deposition of polyaniline included contribution from not only mass but also viscosity and the polyaniline film deposited on electrode surface should be considered to be viscoelastic.
