Abstract
Impedance measurements were made to clarify the mechanism of the propa gation of the electric conductivity with doping protonic acids using c ompressed polyaniline (PAn) specimens. From the simulation of the impe dance data, the equivalent circuit of the PAn was separated from other components. By formulating the dopant concentration into a from funct ion, it was interpreted successfully how new paths for electrons trans fer to other molecular chains appeared and how the jumping frequency i ncreased with dopant concentration.
