CuO and MWCNTs Nanoparticles Filled PVA–PVP Nanocomposites: Morphological, Optical, Thermal, Dielectric, and Electrical Characteristics

Copper dioxide (CuO) nanoparticles and Multiwall carbon nanotubes (MWCNTs) filled poly(vinyl alcohol) (PVA) pyrrolidone) (PVP) blend matrix (50/50 wt%) based polymer nanocomposites (PNCs) (i.e., PVA/PVP:(15-x)CuO(x)MWCNTs for x = 0,1,5,7.5, 10,14, 15wt%) have been prepared employing the solution-cast method. The morphologies of these PNCs are semicrystalline, according to an X-ray diffraction investigation. FTIR, SEM, AFM measurements were used investigate development miscible mix, polymer-polymer polymer–nanoparticle interactions, influence CuO MWCNTs nanofillers on morphology aspects main chain PVA/PVP blend. nanofiller dispersion signposting 14 wt% nanoloading in PVA–PVP significantly enhances crystalline phase, diminishing optical energy gap 2.31 eV. DC conductivity values augment with upsurge level maximum wt%. dielectric electrical characteristics investigated applied frequency range from 1 kHz MHz. enhancement upto leads percolating network through PNCs. These factors boost permittivity substantially, owing decrease nano-confinement phenomenon. rise reduces impedance ac conductivity. having good can be as tunable nanodielectric material electronic devices.
