Abstract An electro- and optically favorable quaternary nanocomposite film was produced by solution-casting nickel oxide nanoparticles (NiO NPs) into polyvinyl alcohol (PVA), pyrrolidone (PVP), poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT/PSS). Based on transmission electron microscopy (TEM) X-ray diffraction (XRD) observations, the synthesized NiO NPs have a cubic phase diameter between 10 45 nm. The complexity interactions observed through XRD patterns, UV–visible spectra, FTIR measurements suggest that are not just dispersed within polymer matrix, but interacting with it, leading to enhanced dielectric properties AC electrical conductivity. From 9 × 3 3.22 Ω, concentrations reduce bulk resistance Rb, indicating more linked conductive channels. tests showed polarized increased polarizability under electric field conditions. incorporation of boosted DC conductivity from 1.25 –6 5.64 –5 S m −1 . mobility boosts linearly frequency. These can lead improved conductivity, energy storage capabilities, overall efficiency nanocomposite, making it promising material for various applications.

Abstract In the present work, sol–gel‐synthesized titanium oxide nanoparticles (TiO 2 NPs) were added to polyvinyl chloride (PVC) and polymethyl methacrylate (PMMA) create polymer nanocomposites (PNCs) samples. The preparation was carried out via solution casting method. synthesized TiO NPs have a tetragonal anatase phase an average grain size of 15.7 nm. XRD analysis reveals that NPs' addition PVC/PMMA causes decrease in crystallinity PNCs films. Infrared Fourier demonstrated interplay/complexity between blend NPs. UV/visible spectrum showed two absorbance peaks at 278 208 nm, which may result from n → π* π transitions. Also, optical bandgaps for indirect direct allowed transitions decreased with increasing concentration. samples' AC electrical conductivity dielectric properties measured room temperature. As content nanocomposite rises, percolating network begins emerge inside composite, demonstrating obeys Jonscher's law. Additionally, it has been nanoparticle concentration leads higher composite loss constant. These findings suggest possibility using prepared capacitive energy storage optoelectronic devices. Highlights PVC/PMMA‐TiO nanocomposites' films fabricated Adding reduces rising content. conductivity, impedance, characteristics discussed. indicate use samples
