摘要：
Optical properties of polypyrrole (PPY) films electrochemically prepared in different conditions were investigated by FTIR reflectance spectroscopy in the range 200-6000 cm(-1). 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 de conductivity values for PPY(TSO).
