Effect of addition of TiO₂ nanoparticles on structural and dielectric properties of polystyrene/polyvinyl chloride polymer blend

The present study deals with the effect of addition pure titanium oxide nanoparticles (TiO2 NPs) prepared by sol–gel technique on a polystyrene (PS)/polyvinylchloride (PVC) polymer blend composition 50/50 wt. % using casting method. X-ray diffraction (XRD), high-resolution transmission electron microscopy, field emission scanning and energy dispersive x-ray analysis confirmed preparation TiO2 NPs in semi-spherical shapes, average particle size ranging from 7 to 22 nm. structural, optical, dielectric properties nanocomposite films are restudied different tools. In addition, studied. XRD Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy complexation interaction between PS/PVC NPs. HRSEM images reveal that appeared as white spots inside spherical domain matrices. Optical such absorbance, reflection, bandgap energy, refractive index, optical (constant loss) These results revealed create inter-bands valence conduction bands. improves electrical conductivity due charge carrier buildup increased polymeric chain segmental mobility
