Abstract:
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.
