Abstract: Conductivity of electrodeposited polyaniline was measured in-situ during the potential running, which is achieved at a homemade in-situ electrochemistry conductometer(ECC) integrated with a two-band electrode. The electrochemical response and change in resistance were recorded spontaneously. Furthermore, the first order reaction kinetics at various potentials was examined on basis of the changes of resistance, and the aging process of PANI film in the acid solution was also explored.

Key words: Conducting polymer, In-situ electrochemistry, Conductivity, Reaction kinetics
