Fabrication of PVA Fibers Loaded with Fe₃O₄ Nano Particles Using Electrospinner

Abstract:

It has been studied the fabrication of a sheet made of polyvinyl alcohol (PVA) fibers loaded with Fe₃O₄ nanomagnetic materials using an electrospinning technique. The solution for the electrospinner was prepared by stirring nano powder of Fe₃O₄ with a solution of 10% PVA in water at room temperature. The electrospinning process was done under fixed of 15 kV DC voltage, using 12 cm distance between the electrodes, and using a syringe needle having a diameter of 0.4 mm. The morphology of fibers was tested using scanning electron microscope (SEM), while the size of particles was tested using transmission electron microscope (TEM). Moreover, the crystallinity of fibers was tested using Laue and x-ray diffraction, while the magnetic moment was tested using a vibrating sample magnetometer (VSM). The result shows that the PVA sheet composing of fibers having a diameter in the range of 130 mm to 250 mm, accommodating Fe₃O₄ nano particles in the range of 15 mm to 25 mm, indicating a partial superparamagnetic property.
