The crystalline nanostructure of intrinsically conducting polymers is formed via an all‐solution process, leading to a highly conducting state. H 2 SO 4 post‐treatment induces a significant structural rearrangement in PEDOT:PSS films, developing crystalline nanofibrils with a stoichiometrically optimal amount of PSS, and this dramatically increases conductivity up to σ dc ≈ 4380 S cm −1 . The highly conductive PEDOT:PSS exhibits potential as a transparent electrode in printable optoelectronic devices, as described by K. Lee, S. H. Lee, and co‐workers on page 2268.
