Abstract Carbon nanosphere / Polyvinyl alcohol/Polyacrylamide (CNS/PVA/PAM) nanocomposite films prepared via a solution casting method were studied for their structural and dielectric properties. Scanning Electron Microscopy (SEM) images of the CNS/PVA/PAM blends reveal the formation of circular islands of CNS and uniform blending with PVA/PAM matrix. XRD pattern shows a higher value with increase in blending ratio of PVA with CNS. The interaction of the dispersed and preformed CNS particles with the PVA/PAM chain was confirmed by the corresponding vibrational signaturing of PVA/PAM through FTIR. The dielectric constant increased from [K = 134, 2K Hz, 305 Kelvin] to [K = 438, 2KHz, 333 Kelvin] and the composite films exhibited a high increase in the energy storage efficiency upto 75% (at 2KHz) in the case of 4%CNS /PVA/PAM 50:50 sample.
