Synthesis, Electrical Conductivity, and Dielectric Behavior of Polyaniline/V2O5 Composites

Conducting polymer composites of polyaniline/vanadium pentaoxide PANI/V2O5 (with different initial weight percentage of V2O5) has been synthesized by in situ polymerization method. DC conductivity of compressed pellets has been analyzed in the temperature range 300–550 K and was found to increase wi...
