Poly-N-vinyl carbazole-polyaniline (PVK-PANI) polymer films were chemically synthesized by varying target loadings of aniline content (0.025-0.1 M). The microstructure and thermal stability of the obtained polymers were characterized by transmission electron microscopy (TEM) and differential scanning calorimetry (DSC). The analysis of DC conductivity was measured in the temperature range of 300-500 K, and the conductivity was analyzed by Mott's variable range of hopping model (VRH). The incorporation of aniline into PVK has a positive influence on the thermal stability and also wields a positive influence on the conducting property of the composites. The conductivity of the polymer films increases with increasing temperature indicating a semi-conducting behavior.
