Description 659-670
Herein we report the Fe3O4-oleate (Fe-OA) nanoparticles (NPs) incorporated poly (vinyl alcohol) (PVA), a series of
highly flexible nanocomposites (Fe-OA-PVA) were prepared by the solution casting technique. The nanocomposites were
fabricated with different weights per cent (0.25 wt. %, 0.5wt. %, and 0.75wt. %, 1wt. %, and 2wt. %, respectively) of
Fe3O4-OA into the PVA matrix. The synthesized nanocomposites were characterized using FTIR, UV–Vis, XRD, Contact
angle, Impedance spectroscopy, SEM and EDS. UV-Vis spectra initially confirmed the interaction of Fe-OA NPs into the
PVA matrix by observing peaks at 223nm, 325nm and 410nm. The FTIR investigation uncovered evidence of an interaction
between the NPs and the PVA polymer matrix. The incorporation of NPs into a polymer matrix shows an enhancement in
various properties due to its nature. The surface properties of the composites were studied using the contact angle technique.
The electric properties of Fe3O4-oleate/PVA nanocomposite films were estimated using impedance spectroscopy. Due to the
dispersion of Fe3O4-oleate NPs into the PVA matrix, we obtained the polarization in dipoles, resulting in good
AC-Conductivity properties. These synthesized nanocomposites may potentially use for electronic applications.
