Evaluation of Charge Transport in Polyaniline by Square Wave Voltammetry

Laboratory of Electroanalytical Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022

Received Date: 8 April 1997
Revised Date: 9 October 1997

The charge transport rate in polyaniline, which was obtained through electropoly-merization by cyclic voltammetry, was evaluated by the square wave voltammetry and the time of scale of voltammetry was defined by AC impedance technique. The results show that the charge transport in polyaniline is controlled by diffusion. The D_app and k⁰ of the redox re-action are determined by COOL algorithm by means of the fast scanning and sampling of the square wave voltammetry.
