Abstract A ternary blend nanocomposite composed of polyvinyl alcohol/cashew gum/polypyrrole (PVA/CG/PPy) with varying contents copper oxide (CuO) nanoparticles was synthesized via an in situ polymerization method, using water as eco‐friendly solvent. Fourier‐transform infrared spectroscopy (FTIR), UV–visible spectroscopy, field emission scanning electron microscopy (FE‐SEM), x‐ray diffraction (XRD), thermogravimetric analysis (TGA), and differential calorimetry (DSC) were used to characterize the nanocomposites. FTIR spectra demonstrated strong intermolecular interactions between functional groups PVA/CG/PPy CuO nanoparticles. XRD patterns revealed that nanofillers arranged a structured manner within matrix. FE‐SEM confirmed uniform dispersion arrangement at concentration 3 wt% TGA DSC results showed addition improved both thermal stability glass transition temperature Electrical properties content up wt%, resulting enhanced conductivity, increased dielectric constant, reduced activation energy. The highest tensile strength, 13.76 MPa, also observed this concentration. However, declined beyond due agglomeration, making ideal for maximum performance. This study highlights potential PVA/CG/PPy/CuO nanocomposites applications requiring electrical stability, particularly flexible electronics energy storage devices. Highlights Eco‐friendly synthesis biopolymer films Improvement morphological, optical films. magnify pristine Conductivity characteristics: frequency dependence explored. films: pliable contenders unveiling industrial potentials.
