Abstract
Fibers of polyethylene oxide were fabricated and analyzed via electrospinning process. High power supply was used to generate greater field needed for the continuous electrospinning. The effects of the different parameters such as high voltage, concentration of PEO-CHC13 solution, and the distance between the anode and the cathode, in the thickness of the fiber were studied. Scanning electron microscope (SEM) was used to determine the surface morphology, Fourier Transform Infrared (FTIR) Spectroscopy was used for compositional characterization, and Differential Scanning Calorimetry (DSC) was used for thermal analysis of the electrospun fiber. Results showed that at increasing concentration of PEO-CHC13 solution, the fabricated fiber experienced a bimodal fiber size distribution, ribbon-like and reduced junctions on the structure of the fiber. At increasing voltages the thickness of the fiber was increased as well as the number of defects and at increasing distances fiber diameter was increased. Also, results showed that the crystallinity and the chemical composition of PEO were not affected by the electrospinning process.
