Solvent Doping and Post-Treatment Process for Poly(3,4 ethylenedioxythiophene):poly(styrene sulfonate) |
| 초록 |
The high cost, brittleness, and high temperature processing of indium tin oxide (ITO), commonly used in optoelectronic applications, boosts a search for alternative electrode technologies. The conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is in particular regarded as a promising electrode material due to its good optoelectronic properties and mechanical flexibility. In this work, we report 1,3-dimethyl-2-imidazolidinone(DMI) as a solvent for PEDOT:PSS for improving the conductivity of films. The electrical and optical performance of PEDOT:PSS films with the new solvent is compared with those of films doped with a conventional solvent. Moreover, a solvent post-treatment is performed to further improve the conductivity of PEDOT:PSS films. The post-treated PEDOT:PSS films shows a significantly reduced sheet resistance compared to untreated films. In addition, the PEDOT:PSS films are adopted as a bottom electrode for organic light-emitting diodes. |
