Synthesis and characterization of novel bio-nanocomposite of polyvinyl alcohol-Arabic gum-magnesium oxide via direct blending method
A B S T R A C T
Due to the significance growth in application of polymer-based nanocomposites, different methods of synthesis
and different reinforces have been studied in recent years for specific purposes. In this study, using the direct
blending process, polyvinyl alcohol-arabic gum-magnesium oxide nanocomposites were synthesized. These
synthesized nanocomposites were investigated using Fourier transform infrared spectroscopy (FTIR), X-ray
diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray energy diffraction (EDS) spectroscopy,
X-ray surface elemental mapping (X-Ray Map), transmission electron microscopy (TEM), ultraviolet
–visible (UV–vis) spectrophotometry and thermal gravimetery analysis (TGA). The results revealed that size
distributions of magnesium oxide nanoparticles and synthesized nanocomposites were between 25 40 nm and
20 90 nm, respectively. Elemental map results show the magnesium oxide nanoparticles were well distributed
on polymer matrix walls.
