|Abstract:||Ternary MnFe2O4/graphene/epoxy nanocomposites have been synthesized using chemical co-precipitation and solid state methods having different concentration of graphene. The obtained ternary nanocomposites and pure MnFe2O4 have been characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and impedance spectroscopy to obtain the structural, morphological and dielectric properties. The crystallite size of MnFe2O4 has been calculated using Scherer formula, which was found to be 1.3 nm. The agglomeration of particles with surface roughness was obtained by SEM analysis. The device has been fabricated using silver coating in terms of capacitor to characterize dielectric properties. It has also been observed from dielectric analysis as concentration of graphene increases from 1% to 10%, the value of gradient of dielectric decreases and also loss tangent decreases on increasing concentration of graphene.|
