FTIR reflectance studies of electrochemically prepared polypyrrole films

. The effects of some relevant electrochemical parameters (the electrolyte, the polymerization current density, and the deposition time) on the reflectance spectra of polypyrrole are reported. The optical constants for polypyrrole films were calculated from the reflectance spectra by Kramers–Kronig technique. The decrease of the electropolymerization current density and film thickness results in an increase of the reflectance and dc conductivity values for PPY(TSO).
