The present work includes a study on the transport mechanism in Zn doped polyaniline conducting
polymer. PANI is one of the most conducting polymer in which the transition takes place between migration of proton
and polaron.
The yield of PANI was higher than 90% in all cases. The doping element was ZnCl2. The synthesized sample of PANI has
been characterized by using FTIR (Fourier Transform Infrared) Spectroscopy and IR, DC electrical conductivity is
measured for knowing the conduction mechanism. We have measured DC electrical conductivity of each sample at
different temperature. The plot of log σ verses 1/T is linear for all ZnCl2 doped sample. The activation energy is
estimated from this plot and found to be 0.1956 eV for 0.274 vol fraction of ZnCl2 sample. The structure characterization
is studied via FTIR and found have maximum peak value 3672.47cm-1
indicate the O-H type of stretching. We have
measured DC electrical conductivity of each sample and thickness.
