Synthesis and improved optical, electrical, and dielectric properties of PEO/PVA/CuCo2O4 nanocomposites

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 15, 2024

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.
