Abstract
Provided are an electroconductive polymer suspension solution and a method for producing the same, which has excellent adhesion to a substrate and excellent liquid resistance and which can provide an organic material having high electroconductivity. An electroconductive polymer suspension solution of an exemplary embodiment of the invention contains an electroconductive polymer, at least one kind of a water-soluble polyhydric alcohol, and at least one kind of a water-soluble organic substance having two or more functional groups which can be polycondensed with the water-soluble polyhydric alcohol. The electroconductive polymer suspension solution can be produced by collecting an electroconductive polymer which is obtained by chemical oxidative polymerization of a monomer giving the electroconductive polymer by using an oxidant in a solvent containing an organic acid or a salt thereof as a dopant, by contacting the electroconductive polymer with an oxidant in an aqueous solvent containing a polyacid, and further by mixing at least one kind of a water-soluble polyhydric alcohol and at least one kind of a water-soluble organic substance having two or more functional groups which can be polycondensed with the water-soluble polyhydric alcohol.
