Fabrication and Enhanced Dielectric Properties of PVA–Cr2O3–Sb2O3 Nanocomposites for Electrical and Electronics Applications

In present work, nanocomposites films have been prepared from Cr 2 O 3 -Sb 2 O 3 -nanoparticles-doped PVA to exploit in different electrical and electronics applications.The dielectric properties of PVA-Cr 2 O 3 -Sb 2 O 3 nanocomposites were tested at frequency ranged from 100 Hz to 5 MHz.The experimental results confirmed that both the dielectric constant and the dielectric loss of PVA-Cr 2 O 3 -Sb 2 O 3 nanocomposites were reduced, whereas the electrical conductivity was increased with raising the frequency.The dielectric constant, dielectric loss, and A.C. electrical conductivity of PVA were increased with raising the Cr 2 O 3 -Sb 2 O 3 -nanoparticles' concentration.The results illustrated that the PVA-Cr 2 O 3 -Sb 2 O 3 nanocomposites can be suitable in different electrical and electronics applications.
