Summary: | PROBLEM TO BE SOLVED: To obtain a stable, electroconductive polymer/dopant complex organic solvent dispersion which is obtained by dispersing an electroconductive polymer and a dopant in an organic solvent.SOLUTION: The method for producing the electroconductive polymer/dopant complex organic solvent dispersion having a water content of ≤20 wt.% is characterized by removing water by spray drying from an aqueous dispersion of an electroconductive polymer/dopant complex (A) to thereby give a dry solid, and by carrying out dispersing treatment after adding to the dry solid an organic solvent (D) and a dispersing agent (B) containing at least one kind selected from the group consisting of amines and nonionic surfactants. According to another embodiment, the method for producing the electroconductive polymer/dopant complex organic solvent dispersion having a water content of ≤20 wt.% is characterized by adding a precipitating agent (C) or an organic solvent (D) to an aqueous dispersion of the above (A), removing water from the resulting gelatinous swollen body, adding the organic solvent (D) and the above dispersing agent (B), and carrying out dispersing treatment. |
