Abstract

Herein, titanium dioxide (TiO₂) nanoparticles (NPs) were prepared via the sol–gel technique; then, they were incorporated into a ternary blend polymer matrix to design polymer nanocomposite (PNC) films through the solution casting technique. The ternary blend polymer matrix consisted of polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), and carboxymethyl cellulose (CMC). X-ray diffraction (XRD) analysis revealed reductions in the crystallinity structure of the polymer matrix after adding TiO₂ NPs. The optical study manifested increases in the refractive index and reduction in the optical bandgap values, which reduced from 4.97 eV for the pure polymer blend to 4.77 eV for the PNC film at TiO₂ content of 3 wt%. Additionally, the transmission edge gradually shifted towards lower energy. The PNC films exhibited considerable improvements in the dielectric constant (ε′), dielectric loss (ε′′), dielectric moduli (M′ and M′′), and electrical conductivity characteristics over the range of frequency range from 0.1 Hz to 10 MHz. The addition of TiO₂ NPs improved the electrical conductivity and dielectric constant significantly. The electrical conductivity increased by over ten times compared to the pure ternary polymer blend, and ε′ also rose four-fold at 100 Hz. The enhancement in the electrical and dielectric parameters of the PNC films after adding TiO₂ nanofiller could indicate the suitability of these samples for flexible-type energy storage applications, such as dielectric capacitors.
