Document Type and Number:
Japanese Patent JP2021195437
Kind Code:
A
Abstract:
To provide a conductive polymer aqueous solution for producing an electrolytic capacitor having property excellent in low ESR while maintaining a high capacity, and a conductive polymer film.SOLUTION: There is used a conductive polymer aqueous solution containing 0.01-10 wt.% of polythiophene (A) including at least one structural unit selected from the group consisting of a structural unit represented by formula (3), and a structural unit having a resonance structure of a thiophene ring main chain, and sulfonated, and 0.001-20 wt.% of a sulfonic acid compound (B) having 1-3 sulfonic groups. In the formula (3), R2 is a hydrogen atom, an alkyl group, a fluorine atom, or the like, m is an integer of 1-10, and n is 0 or 1.SELECTED DRAWING: None
