Among the conducting polymer, PEDOT:PSS has received a great attention due to the commercial potential such as solution processability, good mechanical ductility and high optical transparency. For these reasons, the PEDOT:PSS films are applicable to a wide range of applications. However, it is not suitable for direct application without any post-treatments because the sheet resistance increases when the PEDOT:PSS films are exposed to the atmosphere. In this study, Imidazole was added to PEDOT:PSS solution as antioxidant in order to overcome these disadvantages. We investigated the electrical stability of the PEDOT:PSS films according to the acidity. Fabricated PEDOT:PSS Films were characterized through a variety of analysis, including UV-Vis-NIR optical absorbance spectrometry, XPS, and Raman spectroscopy. Improved stability and optical properties of PEDOT:PSS films are suitable for a numerous application. |
