Abstract
Disclosed is a conductive polymeric ink composition, wherein pH of the ink composition can be adjusted to a desired neutral pH value while maintaining dispersibility of PEDOT:PSS (Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)) used as a main component of the ink composition, thereby solving problems due to strong acidity, including a reduction in the lifetime of devices. Furthermore, a transparent conductive polymer thin film formed from the ink composition has low haze, low surface resistance and high conductivity, compared to thin films manufactured conventionally.
