  • Method of manufacturing highly conductive polymer thin film including plurality of conductive treatments
    Patent number: 11708499
    Abstract: A method of manufacturing a highly conductive polymer thin film is proposed. The method includes a step of coating a substrate with a first dopant solution including a polymer material and a first dopant to form a conductive polymer thin film subjected to first conductive treatment; and a step of performing second conductive treatment using a second dopant solution including pyronin B on the conductive polymer thin film to form a highly conductive polymer thin film.
    Type: Grant
