This study investigates the development of novel nanocomposite films based on a blend polyethylene oxide (PEO) and polyvinyl alcohol (PVA) loaded with varying weight percentages copper cobaltite nanoparticles (CuCo2O4 NPs). The primary objective was to fabricate these nanocomposites using solution casting technique explore influence CuCo2O4 content their structural, optical, electrical, dielectric properties. Spinel-type NPs were synthesized via hydrothermal method incorporated into PEO/PVA blend. X-ray diffraction (XRD) analysis revealed transformation polymer matrix towards an amorphous state increasing content. UV–Vis spectroscopy studies demonstrated decrease in both direct indirect band gaps nanocomposites, suggesting potential applications optoelectronic devices. Impedance measurements significant enhancement ionic conductivity (three orders magnitude higher than pristine blend) for film containing 1.8 wt% CuCo2O4. real permittivity (ε′) imaginary (ε″) exhibited frequency due interplay various polarization mechanisms.

Abstract In this electronic era, there is a demand to switch from conventional polymers conducting biopolymers. We developed biopolymer nanocomposites of cashew gum (CG) and polypyrrole (PPy) with zinc oxide (ZnO) nanofillers [CG/PPy/ZnO] via in‐situ oxidative polymerization using sustainable solvent. These were characterized Fourier‐transform infrared spectroscopy (FTIR), UV–visible spectroscopy, field emission scanning electron microscope (FE‐SEM), differential calorimetry (DSC) thermogravimetric analysis (TGA). The FTIR signal at 855 cm −1 confirms the successful inclusion ZnO into biopolymer. UV–vis absorption blend nanocomposite increases nanoparticle doses. Among various nanocomposites, least bandgap energy was observed for 7 wt% loading. FE‐SEM revealed homogeneous dispersion in CG/PPy ZnO. TGA DSC demonstrated that CG/PPy/ZnO have better thermal stability glass transition temperature than pure polymer blend, indicating enhanced properties. CG/PPy/7 showed highest conductivity, 4.62 times greater pristine 100 Hz. Dielectric constant, activation energy, AC conductivity dielectric loss measurements outperformed blend. Complex impedance increased rising temperature. Overall, exhibit superior optical, morphological, thermal, electrical, properties, making them promising storage optoelectronic applications. Highlights Ecofriendly synthesis Enhancement structural, properties temperature‐dependent are summarized. Blend shows higher constant suitable applications
