Electrochemically active multilayers of self doped polyaniline films were prepared by the ionic interaction between poly(aniline N-butanesulfonate) (PANBUS) and polyethylene imine. Kinetic constant and free energy of the PANBUS adsorption were calculated to be 2.3/M.sec and -5.4 kcal/mole, respectively from the analysis of QCM. The prepared film showed the characteristic cyclic voltammogram of polyaniline and EQCM study of the multilayered film indicated that the mass change during oxidation and reduction was independent on the cations and anions of the used electrolytes.
