Abstract

We report the results of temperature (T) dependence of dc conductivity (σ_dc) for polyaniline (PAN) pellet samples with various dopants (BSA, NSA, TSA, and CSA) in organic solvents (m-cresol, CHCl₃, BeOH) and the mixtures of PAN-DBSA (CHCl₃) and PAN-BSA (m-cresol). σ_dc(7) of PAN pellets varies with dopants in the same solvent. However using different solvent, σ_dc(T) with the same dopant dramatically changes, which indicates that transport properties, can be controlled by both dopants and solvents. The mixture of PAN-DBSA (CHCl₃) and PAN-BSA (m-cresol) induces the increase of σ_dc and the variation from the insulating regime to the critical one.
