Paper Abstract

The fabrication and characterization of conductive and aligned polymeric nanofibers using polypyrrole (PPy) and poly ethylene oxide (PEO) were reported. To improve the structural and electrical properties of the nanofibers, composite materials containing a conducting polymer alloyed with a non-conducting polymer have been proposed. A series of aligned nanofibers using pure PEO and its composite with conducting polymer PPy were produced. By separating the metal target plates, the resultant electric field between the grounded base/collector plates and the charged syringe can be split. This divergence in the electric field facilitates the ordered placement of the nanofibers. Ordered, continuous nanofibers have been realized as large as seven millimeters in separation. The ratio of length to diameter of the aligned fibers can be measured in μm/nm units. Our highest observed value is 46.6μm/nm. The structural properties of these aligned nanofibers have been performed utilizing Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). The characterization of the aligned continuous nanofibers revealed diameters approaching 150 nanometers and the appearance of standard and some new absorption bands for PPy and PEO confirms the composite formation.
