Temperature Dependence of THz Conductivities of Polyaniline Emeraldine Salt/Bentonite Pellets

The THz conductivities of Polyaniline Emeraldine Salt/Bentonite pellets were studied from 80 K to 290 K. Results show that the conductivities increase with increasing temperature. The negative imaginary conductivities reflect backscattering. The complex conductivities were fit by the combined Drude-Smith-Lorentz model. The conduction mechanism in the pellets appear to follow coupling between charges and localized vibrations.
