title: In situ XAS characterization of the electrochemical insertion of copper in polypyrrole films.
abstract: We report the electrochemical insertion of copper in polypyrrole films followed by XAS spectroscopy. Depending on the applied potential the copper remains as an ionic form like Cu(+n)-(OSO3-)n. For more reductive potentials metal particles are synthesized. Small particles with an estimated average diameter of 20 A were obtained.
