Abstract: In the present paper we are reporting the synthesis, characterization, DC conductivity and activation energy of polyaniline (PANI) with cadmium oxide (CdO) composites at different weight percentage. PANI-CdO composites were synthesized by insitu chemical oxidation polymerization method using Ammonium peroxydisulfate (APS) as an oxidizing agent and are characterized using XRD, SEM and FTIR to investigate the structure and surface morphology of composites. The DC conductivity and activation energy are studied as a function of temperature in the range of 50 - 1500C. The DC conductivity increased as temperature increases showing semiconducting nature of PANI and CdO composite.
Key words: DC electrical conductivity, polyaniline composite, SEM, XRD and FTIR, activation energy.
