METHOD FOR PRODUCING CONDUCTIVE POLYMER FILM

PROBLEM TO BE SOLVED: To provide a method for producing a conductive polymer film having excellent processability. SOLUTION: This method for producing the conductive polymer film is characterized by comprising a first process for dissolving a lithium salt in an organic solvent, a second process for gradually adding and dissolving a conductive polymer in the lithium salt-dissolved organic solvent obtained in the first process to obtain a dark blue solution, a third process for coating the dark blue solution obtained in the second process on a flat plate in a constant thickness, and a fourth process for drying the solvent contained in the solution coated in the third process. Since the conductive polymer film can directly be obtained from the solution by the present method, the conductive polymer film can not only be processed into a thin film but also be adjusted to an arbitrary thickness, if necessary. Since the conductivity of the film can further be adjusted by changing the kind and concentration of a salt to be used, the conductive polymer film can be applied to various fields in response to the purposes of use, such as electronic parts or electric parts.
