Abstract
Calcium Ferrite – Polyvinyldene Fluoride – Hexafluoro Propylene (CFO-PVDF-HFP) composite nanofibers were prepared by electrospinning method. Magnetostrictive CaFe2O4 nanoparticles were added to PVDF-HFP ferroelectric polymer in different concentrations. A systematic study on the structural, morphological, electrical properties of the electrospun nanofibers were carried out. X-ray Diffraction were conducted to evaluate the ferroelectric β-crystalline phase of the composite fibers. The enhancement of the electrical properties of the electrospun nanofibers could be observed after the addition of nanoparticles in the polymer matrix. The prepared CaFe2O4 − PVDF-HFP nanofibers possess excellent dielectric constant at room temperature. The excellent dielectric constant and low loss of these composite nanofibers make them applicable in modern energy storage devices.
