The Dielectric Properties of (PVA-PEG-PVP-MgO) and (PVA-PEG-PVP-CoO) Biomaterials

In this paper, study of dielectric properties of two types of nanocomposites are (PVA-PEG-PVP-MgO) and (PVA-PEG-PVP-CoO) in frequency range (100 Hz- 5 MHz). The (PVA-PEG-PVP-MgO) and (PVA-PEG-PVP-CoO) nanocomposites have been prepared by casting technique. The dielectric parameters (dielectric constant, dielectric loss and A. C electrical conductivity) are increasing with the increase of concentrations of magnesium oxide and cobalt oxide nanoparticles. Also, the dielectric properties change with increasing of the of frequency of applied electrical field.
