According to the TiO2 deposition, an interface formed between those TiO2 nanoclusters and the PVA polymer matrix, and the polymer network's overall packing density has decreased. Due to increased interaction among the surface of the nanoparticles of TiO2 and side chains for the PVA polymer matrix, the TiO2 loading concentration shortens the lifespan of the o-Ps. In experiments using Fourier Transform Infrared Spectroscopy, this has been proven.Studies utilizing scanning electron microscopy shows that clustering of nanoparticles results from greater levels of nanofiller loading cause the nanoparticles to aggregate.PVA/TiO2 nanocomposites with greater AC/DC conductivity were produced using polymer at lower TiO2 concentrations indicates that ions and charge carriers are more mobile. Because of increased ion aggregation caused by higher TiO2 concentrations, the conductivity decreases, indicating a reduction in the conductive channel for ion and electrical charge carrier mobility. 0.3 wt% TiO2 and up to 1.0 wt% PVA, a higher dielectric constant and higher loss of dielectric are indicators of increased dipole polarization. Due to the creation of thin, immobile nanolayers and the subsequent increase in polymeric chain mobility, the dielectric constant is thought to have decreased with the addition of 0.3 weight percent of TiO2.
