Abstract :
Polyaniline (PANI) thin film on alumina was prepared by the chemical oxidation of aniline with ammonium peroxydisulphate in acidic aqueous medium. DC conductivity, microwave transmission and reflection, shielding effectiveness of the conducting PANI films is reported. The microwave system used for the measurement of transmittance and reflectance was the X-band (8.2 to 12 GHz) waveguide reflectometer.
