Fabrication and Characterization of Electrospin PAni/Fe3O4/PVA Nanofiber Composites for Telecommunication Engineering
Abstract
The synthesis of conducting polymers has opened new possibilities for the research community for their applications towards microwave absorption in telecommunication engineering. Polyaniline has been one such conducting polymer whose synthesis does not require any special equipment or precautions. Such conductive polymer generally, show highly reversible redox behaviour with a noticeable chemical memory and hence have been considered as prominent new materials for the fabrication nanofibers that could be used in many applications particularly for telecommunication engineering. The current work presents a successful fabrication of Polyaniline / Magnetite / Polyvinyl alcohol (PAni/Fe3O4/PVA) nanofibers composites using electrospinning methods. Field Emission Scanning Electron Microscope (FESEM) was employed to investigate the composites nanofiber’s morphology and TEM was also used to confirmed the present of Fe3O4 nanoparticles in the composites nanofiber, where the nanofibers diameter were investigated and found to be approximately 141 nm as estimated by image-J computer software analysis. Fourier-Transformation Infrared Spectroscopy (FTIR) study confirmed the presence of both Fe3O4 nanoparticles and PAni in the nanofiber structure. The X-ray diffraction (XRD) pattern of Fe3O4 nanoparticles and PAni/Fe3O4/PVA nanofiber materials shows the characteristic behaviour of both amorphous and crystalline phase by indication of the peaks at 2θ = 23.12o, 24.14o and 35.13o in the prepared materials.
