The relation between the composition, structure and absorption properties of ultra-high frequency radio waves of poly(vinylidene fluoride)/magnetite nanocomposites

    In the presented work, nanocomposites based on poly (vinylidene fluoride) (PVDF) and magnetite Fe3O4 nanoparticles were prepared. The structure and content of nanocomposite materials were studied by using scanning electron microscope (SEM), atomic-force microscope (AFM) and X-Ray diffraction (XRD). Magnetic properties of PVDF+Fe3O4 nanocomposites have been studied upon increasing nanoparticle content in polymer matrix upto 20%, revealing superparamagnetic behavior as Fe3O4 nanoparticles in polymer matrix act out like single-domain particles. It has also been observed that PVDF+Fe3O4-based nanocomposites can absorb the electromagnetic waves in the high frequency range 0.1–30 GHz. It has been shown that the absorption of high frequency radio waves by PVDF+Fe3O4 nanocomposites can be explained by the different molecular structures and also by the scattering of the radio waves at the boundary of nanoparticle-polymer matrix.
