Abstract
This work describes the development of polyaniline-Co3O4 composites by ex situ polymerization technique. The composites with varying Co3O4concentration were subjected to morphology and structural using scanning electron microscopy and X-ray diffraction. The room temperature conductivity and dielectric studies were conducted as a function of frequency. The conductivity of the composites tends to increase with increase in the frequency indicating hopping of charge carriers as a dominant mechanism.The variation of dielectric constant of all composites with respect to the frequency was analysed at room temperature. The dielectric constant was found to increase with the increase in Co3O4concentration and was found to highest for composite with 45% Co3O4. The thermogravimetric analysis carried out to study the thermal stability showed that the composite with highest Co3O4concentration displayed better stability.

Keywords- PANI-Co3O4, Scanning electron microscopy, X-ray diffraction.
