Structural, Dielectric, and Optical Properties for (PVA/PVP/CuO) Nanocomposites for Pressure Sensors

Films of PVA–PVP doped with CuO nanoparticles have been fabricated. The structure, dielectric and optical characteristics are studied for optoe-lectronic fields as pressure sensors. The results indicate that the dielectric parameters of PVA/PVP blend improve with raise in CuO-nanoparticles’ ratios. The optical-characteristics’ measurements explain the enhancement in optical characteristics with rising of the copper-oxide content. The applications’ results indicate to the prepared nanocomposites have good sensitivity for pressure.
