Enhancement of Structural and Dielectric Properties of PVA–BaTiO3–CuO Nanostructures for Electronic and Electrical Applications

In this work, we study the effect of the barium titanate oxide and copper oxide nanoparticles (NPs) on polyvinyl alcohol (PVA) with different weight percentages (0, 2, 4, 6 wt.%).The solution casting technique is used to make the samples.Images taken with an optical microscopy reveal that the distribution of NPs in the mixture is homogeneous, and BaTiO 3 -CuO NPs exist in a continuous network within the, polymer at the concentration of 6 wt.%.FTIR spectra, display a variation in bonds' positions and intensity.This indicates the non-chemical interaction between the polymer and BaTiO 3 -CuO NPs.The experimental results show, when the concentration of BaTiO 3 -CuO NPs within the samples rises, their dielectric constant and dielectric loss are increased, while they are decreased by increasing of frequency.A.C. electrical conductivity is increased with increasing of frequency and concentration of BaTiO 3 -CuO NPs.Finally, the results show that the PVA-BaTiO 3 -CuO nanostructures may be useful in a variety of nanoelectronics devices.
