PVDF-Fe3O4 nanocomposites: spectroscopic investigations
Nanocomposites have been prepared by melt mixing, loading the polyvinylidene fluoride matrix with various concentrations of magnetite. Wide Angle X-Ray Scattering, Raman, Fourier Transform Infrared, and Electron Paramagnetic Resonance spectroscopy were used to investigate these nanocomposites. Wide Angle X-Ray Scattering revealed that α is the dominant crystalline phase of the polymeric matrix irrespective of the loading with magnetite. Wide Angle X-Ray Scattering investigations on the dependence of the line positions and widths on the loading with magnetite are reported. Raman and Fourier Transform Infrared spectroscopy confirmed that the as-obtained nanocomposites consist of α polyvinylidene fluoride. The main Raman lines were identified, and the dependence of their parameters (line position and widths) on the loading by magnetite was reported. Raman and Wide Angle X-Ray Scattering data demonstrated a strong interaction between the matrix and the nanofiller. Electron Paramagnetic Resonance spectra of these nanocomposites reflect strong anisotropic electron interactions among the nanofiller’s electrons.
