Abstract
Development of PVA-MF blends encapsulated with NiO nanoparticles to prepare moisture-resistant polymer nanocomposite films. The preparation of PVA-MF blend was carried out by blending of MF resin and prepared PVA solutions in various ratios (2% PVA and different volumes of MF, i.e., 1.3 ml (N1), 2.2 ml (N2), 2.7 ml (N3), 3.6 ml (N4), and 4.4 ml (N5)] to optimize their ratio for nanocomposite preparation. The nanocomposite films were prepared by dispersion of NiO nanoparticles in the different ratio [N3 (0.03), N3 (0.06), N3 (0.09), and N3 (0.1)] in the optimized PVA-MF blend (N3) system. The structure, physicochemical properties, and morphology of a prepared blend and polymer nanocomposites were characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-visible) spectroscopy, X-ray powder diffraction (XRD), and field emission scanning electron microscopy (FE-SEM). The analysis reveals that the blend and polymer nanocomposite was successfully synthesized. Electrical conductivity of PVA-MF blend (N3) has been dramatically enhanced from 0.0258 ± 0.00129 to 0.3355 ± 0.01678 S/m and reduction in the band gap of nanocomposite from 5.1 to 4.8 eV as compared to blend by doping NiO nanoparticles. The synthesized polymer nanocomposite will be used for the development of new material in electrical fields.
