Anomalous behaviour of the electrical properties for PVA/TiO2 nanocomposite polymeric films
In the present study, the fabricated nanocomposites were prepared by the casting technique by adding titanium dioxide (TiO 2 ) to polyvinyl alcohol (PVA) with different weight percentages (0.037, 0.185, 0.370, 1.852, 3.704 and 37.037 wt%). SEM micrographs declared that PVA polymer matrix contains a...

) to polyvinyl alcohol (PVA) with different weight percentages (0.037, 0.185, 0.370, 1.852, 3.704 and 37.037 wt%). SEM micrographs declared that PVA polymer matrix contains a distributed set of cluster of TiO
2
nanoparticles. AC electrical characteristics and dielectric relaxation of nanocomposite polymeric films in the frequency range 100 kHz–1 MHz were presented as temperature changes from 303 to 413 K. The results indicated that the dielectric performance and electrical properties of the nanocomposites differ anomalously with increasing TiO
2
nanoparticles content. It was demonstrated that there is a stronger temperature-reliance of the dielectric properties of the 1.852 wt% of TiO
2
/PVA nanocomposite polymeric film. Moreover, there is an interfacial polarization effect, which obeys Arrhenius behaviour that increased nonlinearly with increasing temperature at a fixed frequency. The electrical relaxation dynamics containing dielectric was examined. The dielectric properties were investigated through the electric modulus. |
