Abstract The current work is concerned with the study and examination of thermal electrical characteristics polyvinyl alcohol (PVA)/Mn 2 O 3 –reduced graphene oxide (rGO) nanocomposite. Mn –rGO composite was synthesized using a hydrothermal approach technique, then PVA films were strengthened varying amounts nanoparticles (NP) prepared by casting method. Raman analysis applied to polymer ensure complexation between –rGO. Thermogravimetric (TGA) are used investigate effect NP on stability conductivity films. films' raised increasing content in matrix. exhibit an increase from 2.023 × 10⁻⁸ S·cm⁻¹ for pure 1.895 10⁻⁵ PVA‐1.5% –rGO, which arises rise free charge carrier mobility hopping ionic hopping. Furthermore, accordance Arrhenius relation, increases temperature. results nominated present flexible electronic applications.

ABSTRACT This article reports, for the first time, electromagnetic interference (EMI) shielding performance of a flexible PCCCe polymer nanocomposite, which was manufactured using mini twin‐screw extrusion process. In manufacturing nanocomposites, binary blends PVA (polyvinyl alcohol) and CS (chitosan) have been used as host matrix, while CeO 2 nanoparticles (synthesized via sol–gel method) CB (carbon black) in form nanofillers. The incorporation nanofillers matrix verified through XRD analysis, causing expansion crystallite size ranging from 18 to 28 nm along with existing micro‐strain. increased amount has shown an increase absorbance blue shift enhancement refractive index (from 2.09 2.16), reduction optical band gap 4.79 4.03 eV) lowering Urbach energy 1.36 0.33 eV). Blue emission observed confirmed CIE plot studied PL spectra. Thus, it demonstrates unique combination index, reduced gap, lowered energy, blue‐shifted spectra, offering innovative control over properties advanced multifunctional applications. Moreover, Raman spectroscopy reveals presence D, G, D+G peaks at 1361, 1560, 2910 cm −1 due disordered crystal structure carbon atoms. addition structural characterizations, composites were also dielectric effect analysis X‐band frequency range that lies 5G spectrum. High constant loss are claimed high total effectiveness parameter synthesized nanocomposites. nanocomposites exhibit remarkable elevated 90 dB 12 GHz, surpassing other samples investigated study. breakthrough nanocomposite design highlights its potential next‐generation material superior wave absorption EMI
