Abstract Details

2017, Doctor of Philosophy, University of Akron, Polymer Science.
Electrospinning is a facile and low-cost method to produce polymer fibers with diameter ranging from a few microns to a few nanometers. These electrospun nanofibers have shown great potential in the development of novel patterning technology for future flexible electronics. In this research, electrospinning based patterning technology was investigated in transparent electrode and organic field effect transistor fabrication. Transparent electrodes are essential components in assembly of solar cells, displays and touch screens. Using electrospun nanofiber as the patterning mask, the percolated metal nanowire electrode was fabricated with high figure of merit. Both the transmittance and sheet resistance (6 O/sq at 83% transmittance and 24 O/sq at 92% transmittance) of the metal nanowire-based electrode out-perform commercial product Indium Tin Oxide (ITO). In addition, such an electrospun nanofiber patterning method allows the fabrication of metal nanowire electrodes on polymer substrate, making it available for flexible transparent electrode. A flexible transparent electrode was demonstrated in the resistive touch screen. In comparison to the traditional inorganic semiconductors, organic semiconducting materials have the advantages of lightweight, high flexibility and potentially low-cost fabrication process. Using electrospun nanofiber patterning method, it is possible to prepare the organic field effect transistor (OFET) with submicron channel length. In this research, a series of new conjugated polymers have been synthesized. The OFET devices based on electrospun nanofiber patterned channel were fabricated and investigated. It was found that the fiber channel based devices had significantly reduced operating voltage, compatible with low voltage power sources.
