Fabrication of SrTiO3 NPs Doped Polymer Blend and Studying their AC Electrical Characteristics for Piezoelectric Fields

Abstract

Abstract Nanocomposite films of PVA/PAA/SrTiO3 NPs were fabricated for electronic and optic approaches using a low cost method. The AC electrical characteristics of PVA/PAA/SrTiO3 films were investigated. The results showed that the dielectric constant of polymeric blend increases from 5.39 to 7.25, and the dielectric loss increases from 1 to 30. While, the electrical conductivity increases from 5.00E−11 to 2.00E−9 with increasing the SrTiO3 NPs content. Also, the dielectric constant of polymeric blend increased from 5.39 to 8.04, and the dielectric loss increased from 0.377 to 1.21. While, the electrical conductivity increased from 2.09E−11 to 6.70E−11 with increasing the frequency.
