Description
Summary:Magnetoelectric (ME) materials are capable of use in multifunctional devices due to their eccentric properties. Flexibility is a beneficial trait for enabling ME materials to be utilized in advanced device fabrication. We introduced varying weight percentages (4, 8, 16 wt%) of magnetostrictive SrFe 12 O 19 (SFO) nanoparticles into a piezoelectric PVDF-HFP to fabricate flexible magnetoelectric nanocomposite fibers. Structural and morphological modifications of the composite fiber mats were investigated using X-ray diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and Transmission Electron Microscopy (TEM) analysis. Dielectric and Ferroelectric studies were conducted and an exceptional enhancement in the dielectric constant and ferroelectric parameters was observed for 16% of SFO loaded sample. The magnetoelectric coupling coefficient (MECC) improved to 19.9 mV/cm. Oe for the higher filler-loaded composite sample. Additionally, mechanical studies were also done to ensure the flexibility of the composite fiber mats. Graphical abstract
