Abstract
A conductive polymer dispersion of this disclosure includes: a conductive composite containing a π-conjugated conductive polymer and a polyanion; an isocyanurate-based compound; and a dispersion medium for dispersing the conductive composite.
Claims1
A method of producing a conductive polymer dispersion, comprising:
- a precipitation step of adding an epoxy compound to an aqueous dispersion of a conductive composite containing a π-conjugated conductive polymer and a polyanion to precipitate the conductive composite, to thereby form a precipitate;
- a collection step of collecting the precipitate;
- a conductive mixed liquid preparation step of adding an organic solvent to the collected precipitate to prepare a conductive mixed liquid;
- and
- an isocyanurate-based compound addition step of adding an isocyanurate-based compound represented by the following formula (1) to the conductive mixed liquid:
- in the formula (1), R1, R2, and R3 each independently represent a hydrogen atom or any substituent.
