Abstract

The dielectric function of polyaniline (Pani) doped by couple drug/solvent sulphonic camphoracid/dichloroacetic CSA/DCAA is studied in the terahertz range. Numerous films of Pani-CSA/DCAA with different doping level are measured by Terahertz Time-Domain Spectroscopy (THz-TDS). The Fourier transmission spectrum, the permittivity and conductivity are then obtained. The behavior of the dielectric function is analyzed by a Drude modified model and the percolation threshold is deduced from comparative measurements...
