Abstract The Polyethylene glycol (PEG) and Chitosan (CS)/silver nitrate (AgNO 3 ) thin films were prepared by utilizing the casting technique to enhance their optical, dielectric, electrical properties. Their physicochemical characteristics investigated using a variety of techniques. FT‐IR study demonstrates that addition AgNO NPs results in discernible difference intensities locations vibrational peaks all bands, supporting incorporation inside PEG/CS. XRD analysis indicates peak at 2θ = 23.1° broadens strengthens proportionally with increase NPs. This observation suggests into PEG/CS greater degree amorphous compared blend. Additionally, when amount increases PEG/CS, energy band gap decreases, resulting creation localized states between valence conduction bands. These polymer nanocomposite films' conductivity, dielectric constant, loss increased frequency showed variance for various composite concentrations. NPs/PEG/CS can be promising options frequency‐tunable nanodielectrics, flexible substrates, bandgap‐regulated materials upcoming microelectronic, capacitive storage, optoelectronic technologies, according experimental results. Highlights nanocomposites obtained. optical properties calculated. Optical energy‐gap samples was reduced after adding are improved. suggested used storage devices.

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. Notably, incorporating led remarkable improvement energy density compared Additionally, barrier observed. These findings demonstrate successful fabrication PEO/PVA-CuCo2O4 enhanced observed improvements suggest promising materials storage devices potentially like light-emitting diodes.
