The development of flexible and highly conductive transparent electrode materials is of significant scientific and commercial interest. Owing to its brittleness, ITO, the standard transparent electrode material for rigid optoelectronic devices, is poorly suited to the emerging generation of flexible electronic devices. Recently a number of research investigations have looked into the fabrication and characteristics of conducting polymer films for various applications. Conventional conducting polymer films have been fabricated by the wet-process through electrochemical deposition, dispersion, and chemical polymerization of the monomer. In this work, the highly transparent and conductive poly(3,4-ethylenedioxythiophene)(PEDOT) films hybridized with Au nano particles of 5-15 nm sizes were prepared by gas-phase polymerization method as a kind of self-assembling technique. The conductive PEDOT, as a matrix material, was filled between the Au nano dots by self-organization of the EDOT monomer. As a result, PEDOT-Au hybrid films, having high conductivity and uniformity, were directly synthesized. Compared to the traditional film-forming procedures, this process introduced the effective quantum effect for electrical conductivity, increased the conductivity. This PEDOT-Au nano hybrid films have a high transparency up to 80%, and possess a very low sheet resistance of an 80 Ω square-1 at 50-nm thickness. |
