title: Gold-polyaniline composite. Part I. Moving electrochemical interface.
abstract: The controlled growth of gold nanoclusters in polyaniline is predicated by the ability of PANI to switch from conducting to insulating form and by the fact that imine nitrogens form a strong complex with chloroaurate anions. The principal technique used in this study has been chronopotentiometric stripping. The chronopotentiograms indicate that the electrochemical interface for the Pt/Au/polyaniline/electrolyte shifts back and forth from the solution/PANI interface to Au/PANI interface. By adjusting experimental conditions the size and the size distribution of Au clusters can be controlled.
