Abstract: CoFe2O4/MWCNT (CFO/MWCNT) nanocomposites have been synthesized using Co-precipitation and solid state method. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and impedance spectroscopy have been used to determine structural, morphological and dielectric properties of synthesized nanocomposites. The particle size was found to be 3 nm, 3.3 nm and 4 nm for CFO, C-CFO/MWCNT and G-CFO/MWCNT, respectively, using Scherrer formula. Aggregation of nanoparticles has been acquired by SEM analysis. From impedance spectroscopy, it has been observed that the dielectric constant decreases with increase in frequency and dielectric constant and loss both are more for C-CFO/MWCNT nanocomposites than that are for G-CFO/MWCNT nanocomposites.
