Abstract

The conductive thin films of ferric chloride doped poly(3,4-ethylenedioxythiophene) (PEDOT: Fig. 1) were obtained by in situ vapor-phase polymerization method under ambient conditions. Homogeneous thin conductive PEDOT films were uniformly fabricated at nano-level thickness (20-300nm) on the substrates. The surface resistance of the PEDOT films with 300nm thick was enhanced up to 500Ω/sq, and the light transmittance were also increased as up to 95% in case of a film below 40nm thick. The growth of highly ordered conductive PEDOT crystalline microstructure, which high anisotropy, parallel to the substrate film fabricated above 60°C, was observed by atomic force microscopy (AFM).
