Although their formation and reactivity have been extensively studied, their electronic spectroscopy has received significantly less attention..

    Article Snippet: Developing biodegradable polymer nanocomposites with improved electrical and multifunctional characteristics is important for the fabrication of next-generation sustainable materials and devices.. However, the relatively low electrical conductivity and restricted multifunctional properties of polyvinyl alcohol (PVA)-based systems remain significant challenges, requiring suitable modification strategies.. To address these restrictions, copper oxide (CuO) nanoparticles were integrated into a PVA/cashew gum (CG) composite matrix to develop eco-friendly nanocomposite films with enhanced structural, thermal, optical, mechanical, and electrical performance.

In this regard, polyvinyl alcohol has gained significant importance due to its ease of handling, high solubility, and low toxicity.. This work presents the improvement of the thermal diffusivity of polyvinyl alcohol thin films through the physical incorporation of nanofillers, specifically previously synthesized silver nanorods.
