This paper aims to fabricate (polyethylene oxide-polyvinyl pyrrolidone) blend and (poly (ethylene oxide-polyvinyl pyrrolidone-cerium dioxide nanoparticles-manganese dioxide nanoparticles) nanocomposites have been investigated for a pressure sensor. The nanocomposites(NCs) are prepared for different concentrations of polymer blend, cerium dioxide nanoparticles, and manganese dioxide nanoparticles. The electrical properties (dielectricconstant, dielectricloss and A.C electrical conductivity) of (PEO-PVP-CeO2-MnO2)nanocomposites have been studied. The dielectric properties of nanocomposites are examined in the frequency range (100 Hz–5×106 Hz). The experimental results displayed that dielectricconstant, and dielectricloss rise with an increase of the weight percentages of manganese dioxidenanoparticles. The dielectricconstant and dielectriclosses reduce as the frequency increases. The AC electrical conductivity has a high value as the weight percentages of manganese dioxidenanoparticles and the frequency increases. The nanocomposites were examined for the pressure sensors application in the pressure range (80–160) bar. The results showed that the electric capacitance of NCs samples is increased as the pressure increases. Also, the electric capacitance of nanocomposites increases with an increase in the weight percentages of manganese dioxide nanoparticles. Finally, the results showed that the (PEO-PVP-CeO2-MnO2) nanocomposites have a high sensitivity to the pressure.
