Radio Frequency Response of Magnetic Nanoparticle-Doped Yarn

Popis výsledku v původním jazyce

The amount of research with electrospun nanofibers in various fields of science and their use in engineering applications is increasing rapidly. The commercial use of nanofibre technology is intensively investigated mainly in the field of water treatment and environmental remediation, health and biomedical engineering, and energy production and storage. Therefore, a wide range of base materials has been used to synthesize nanofibers with various physical properties. This paper presents the results of experiments on the shielding effectiveness against electromagnetic fields using yarns. The yarns were produced using AC electrospinning based on a needleless spinning-electrode. The optimal frequency of 50 Hz and a high voltage of 40 kV were used to generate the yarn. The poly(vinylbutyral) was chosen as a polymer. Nanoparticles of Fe3O4 were used as the filler. Transmission electron microscopy confirmed good compatibility of the nanoparticles with polymeric nanofibers. The presence of the magnetic dopant in the nanofibers was also reflected in measured magnetization curves. Measurements of Fe3O4 nanoparticle-doped yarn shielding effectiveness in the frequency range from 700 MHz to 3 GHz confirmed a slight shielding effect. © 2020 Polish Academy of Sciences.
