  • Publication number: 20230159766
    Abstract: A conductive polymer composition containing: a composite containing a ?-conjugated polymer (A) and a polymer (B) shown by the following general formula (2); H2O (D) for dispersing the composite; and a water-soluble organic solvent (C). This provides a composition which has favorable filterability and film formability, and which is capable of relieving acidity and forming a conductive film with high transparency. Moreover, since the H2O dispersion of the conductive polymer compound is mixed with an organic solvent, the surface tension and the contact angle are so low that leveling property on a substrate is imparted. The composition is usable in droplet-coating methods. Since an organic solvent having a higher boiling point than H2O is used as the organic solvent, the composition can avoid solid content precipitation around a nozzle and solid content precipitation due to drying between ejecting the liquid material from a nozzle tip and landing on a substrate.
