Abstract
About this talk
In recent times the nanomaterials has been a great attention for their exceptional electromagnetic and dielectric applications. The size and shape dependent tuneable dielectric properties of NZ nanocomposites makes them an attractive material for various future electronics device applications such as mobile, aerospace, wearable and RF antennas. In this study NiO nanoparticles, ZnO nanoparticles and NZ nanocomposites samples have been synthesised by wet chemical method. Dielectric properties such as, permeability, permittivity and dielectric loss tangents and temperature dependence are studied. Nickel nanoparticles and zinc nanoparticles and NZ nano composites are characterised by XRD and SEM. Xray powder diffractometer (XRD) has been used to establish the phase purity and crystal structure. The surface morphology of the samples has been obtained using a scanning electron microscope (SEM). The XRD studies which confirmed the presence of crystal structure of NiO, ZnO and NZ nanocomposite. The NZ nanocomposite particles size is 25 nm compared with ZnO and NiO nanoparticles and are also studied with dielectric constant.
