1) it is evident, that the current-voltage characteristics of the PANI-EB are nonlinear and temperature dependent.
In the electrical field with low intensity, the PANI-EB behaves as an insulator.
The mobility of charge carriers in PANI-EB is influenced by the electric field and the conductivity of polymer can be described by the equation
Therefore, it can be said that Schottky emission is the dominant conduction mechanism in PANI-EB, which is in agreement with the results obtained by other authors (Mathai, 2003; Pelto, 2004).
