“…Pure ZnO has limited electronic and optical applications as pure ZnO has blue light emission which is the least eye sensitive colour and shows more scattering [125]. Pure ZnO has fixed and specific electric properties like bandgap, electron mobility, thermal conductivity, and exciton binding energy.…”

Energy storage devices constitute one of the research areas in recent years. Capacitors are commonly used for the storage of electrical energy. The current research is focusing on not only the improvement in energy density but also the materials which are environment friendly. Polymer composites are known to be technically essential materials owing to their wide range of applications. Enormous research has been devoted to zinc oxide- (ZnO-) based polymer nanocomposites, due to their extraordinary dielectric properties. This review article presents a detailed study of the dielectric properties of ZnO-based nanocomposites. The dielectric constant study includes the effect of transition metals and rare earth metals as a dopant in ZnO. This review gives an insight into the mechanism responsible for the variation of dielectric constant in ZnO nanocomposites due to various factors like size of nanoparticles, thickness of the thin film, operating frequency, doping concentration, and atomic number. The observations have been summarized to convey the mechanism and structural changes involved in the ZnO nanocomposites to the researchers. The deployment of biodegradable nanocomposite materials is expected to open an innovative way for their outstanding electronic applications as storage materials.

The purpose of this study was to determine the effects of carbon nanotubes (CNT), reduced graphene oxide (rGO), and a mixture of the (CNT-rGO) on the structural, mechanical, electrical, and optical properties of low (CSL), medium (MCS) and high-molecular (HCS) weight chitosan. The formed films' structure and physical properties were analyzed using swelling, X-ray diffraction, mechanical testing, and SEM micrographs. The 4-Probe technique showed that chitosan electrical conductivity was improved by six orders of magnitude strongly influenced by the CNT addition. The photoluminescence (PL) studies showed that rGO addition induces a non-radiative process in composites and decreases the PL intensity by nearly 43%. The CNTs in CSL and the mixture in CSL present the best electrical, optical, and swelling degree properties. The composites properties and ease of preparation of the films reported in this work make them suitable for optoelectronic applications due to their electrical conductivity and PL values.
