Document Type and Number:
Japanese Patent JP6842928
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a conductive polymer dispersion liquid, wherein the solid content concentration of a conductive complex included in an aqueous dispersion medium is improved compared to that in the conventional art, and it is suitable for forming a conductive layer having excellent conductivity and a good appearance, and a method for producing the same, and a method for producing a conductive film.SOLUTION: The present invention provides [1] a conductive polymer dispersion liquid that contains a conductive complex containing a π-conjugated conductive polymer and a polyanion, and an aqueous dispersion medium for dispersing the conductive complex, wherein, relative to the total mass of the conductive polymer dispersion liquid, the content of the solid content of the conductive complex is 2.4 mass% or more, and a weight ratio between the π-conjugated conductive polymer and the polyanion is 1:3 or more and 1:5 or less, [2] the conductive polymer dispersion liquid described in [1], wherein the π-conjugated conductive polymer is poly (3,4-ethylenedioxythiophene), and [3] the conductive polymer dispersion liquid described in [1] or [2] wherein the polyanion is polystyrene sulfonate.SELECTED DRAWING: None
