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.
由于基于聚合物的纳米复合材料的应用显著增长，近年来针对特定目的研究了不同的合成方法和不同的增强材料。在本研究中，采用直接共混工艺合成了聚乙烯醇-阿拉伯胶-氧化镁纳米复合材料。使用傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、场发射扫描电子显微镜（FESEM）、X射线能量衍射（EDS）光谱、X射线表面元素映射（X射线图谱）、透射电子显微镜（TEM）、紫外-可见（UV-vis）分光光度法和热重分析（TGA）对这些合成的纳米复合材料进行了研究。结果表明，氧化镁纳米颗粒和合成的纳米复合材料的尺寸分布分别在25-40nm和20-90nm之间。元素图谱结果表明氧化镁纳米颗粒在聚合物基体壁上分布良好。
