Abstract

In the present work, magnetite (Fe3O4) nanoparticles have been prepared by a simple chemical method. Polymer nanocomposites based on the blend between poly vinylamine fluoride (PVDF) and (methyl methacrylate) (PMMA) doped with different concentrations of Fe3O4 nanoparticles have been prepared. The structural, optical, and magnetization properties of the nanocomposite samples were studied using suitable techniques. The X-ray study reflected that the cubic spinal structure of pure Fe3O4 crystal. No small peaks or ripples were found in the X-ray spectra, conforming to good dispersion of Fe3O4 within PVDF/PMMA matrices. The FT-IR analysis demonstrated the miscibility between the PVDF and PMMA blend with the interaction between the polymer blend and Fe3O4. The values of the band gap from UV-Vis study were decreased up to 4.21 eV, 3.01 eV for direct and indirect measurements, respectively. The magnetization was measured as a function of the applied magnetic field in the range of −2000 - 2000 Oersted. The curves of the magnetization indicated a paramagnetic behavior of pure Fe3O4 nanoparticles and PVDF/PMMA-Fe3O4 nanocomposites. The values of saturation magnetization for pure Fe3O4 are nearly 75 emu/g, exhibiting a paramagnetic behavior, and it is decreased with the increase of Fe3O4 content.
磁性(Fe3O4)纳米粒子包埋PVDF/PMMA共混物的光谱、光学和磁性分析
本文采用简单的化学方法制备了磁铁矿(Fe3O4)纳米颗粒。以掺不同浓度Fe3O4纳米粒子的聚偏氟乙烯胺(PVDF)和(甲基丙烯酸甲酯)(PMMA)共混为基础,制备了聚合物纳米复合材料。采用合适的技术研究了纳米复合材料的结构、光学和磁化性能。x射线研究表明,纯Fe3O4晶体具有立方脊柱结构。在x射线光谱中没有发现小的峰或波纹,符合Fe3O4在PVDF/PMMA基体中的良好分散。FT-IR分析表明PVDF和PMMA共混物之间存在混相,共混物与Fe3O4之间存在相互作用。紫外-可见光谱直接测量带隙值为4.21 eV,间接测量带隙值为3.01 eV。磁化强度作为外加磁场在- 2000 - 2000奥斯特范围内的函数进行了测量。磁化曲线表明,纯Fe3O4纳米粒子和PVDF/PMMA-Fe3O4纳米复合材料具有顺磁性。纯Fe3O4的饱和磁化强度接近75 emu/g,呈现顺磁性,随Fe3O4含量的增加而减小。
