Patents Method for preparing conductive polymer solution and conductive polymer film

The present invention relates to a method for preparing a conductive polymer solution and a conductive polymer film, which may increase the doping ratio of a conductive polymer solution and remove ions that have not been removed after the reaction in the conductive polymer solution, unreacted monomers, unreacted oligomers, and polymer electrolytes in excess, through a simple process, and may increase the electrical conductivity of a film prepared by using the conductive polymer through this.
