논문초록 Conducting polymer is expected to the versatile materials for organic solar cell, light emitting display, etc. Particularly, PEDOT:PSS is one of the most commercial conjugated polymers because of its transparency, solution-processiblility and flexible properties. But, it has deficient electrical conductivity compared to inorganic materials like FTO or ITO, based on ordered structures. Most of organic materials have low crystallization degree and amorphous structures. In this work, we get 2-D structured PEDOT:PSS film, improved 3~4 times electrical conductivity through repeated sulfuric acid etching process to overcome this problem. The XPS, raman spectra, optical properties(Transmittance, Haziness, b*… etc.), XRD, AFM and electrical conductivity of the PEDOT:PSS were evaluated. This can be used as transparent electrode materials for electronic devices like organic thin film transistor or OLED.
