Abstract:
The present invention relates to a method of manufacturing a metal nano fiber electrode array using arranged metal nano fibers. The method may comprises the step of: preparing a metal precursor/organic polymer composite solution by mixing a metal precursor and an organic polymer with distilled water and an organic solvent; forming metal precursor/organic polymer composite nano fiber patterns arranged in a continuously connected form on a substrate by injecting a metal precursor/organic polymer solution into a nozzle of an electric field auxiliary robotic nozzle printer, applying an electric field to the nozzle, discharging the composite solution vertically from the substrate when the solution forms a talyor cone at an end of the nozzle, and moving the substrate when a solidified nano fiber in a continuously connected form is extracted; and forming arranged metal nano fiber patterns formed of metal nano grains by thermally processing the arranged metal precursor/organic polymer composite nano fiber patterns to thermally decompose the organic polymer and reducing the metal precursor into the metal nano grains. Accordingly, a location and a direction of the metal nano fiber pattern can be precisely adjusted and the metal nano fiber pattern can be arranged in a desired direction. Further, a nano fiber electrode array having an improved solution of the metal electrode pattern can be provided. Furthermore, a method of manufacturing a nano fiber electrode array, of which a process is prompt and simplified, can be provided. The nano electrode fibers can be utilized as electrodes of, for example, an electric field effect transistor, an organic light emitting diode, and an organic solar cell.
