| 摘要 |
The present invention relates to a conductive polymeric ink composition and, more specifically, to a pH-adjusted conductive polymeric ink composition, characterized in that the pH of the ink composition is adjustable to a desired range by increasing the pH of the ink composition to neutral while maintaining the dispersibility of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), which is a main component of the ink composition, thereby solving problems, such as shortening the lifespan of devices due to strong acid, and a transparent conductive polymer thin film manufactured using the ink composition has a lower haze value than thin films manufactured by existing methods, and retains excellent electrical conductivity due to low sheet resistance. |
