Transparent Electrodes: Highly Conductive PEDOT:PSS Nanofibrils Induced by Solution‐Processed Crystallization (Adv. Mater. 14/2014). (April 2014) - Kim, Nara
Abstract The crystalline nanostructure of intrinsically conducting polymers is formed via an all‐solution process, leading to a highly conducting state. H2SO4 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 σdc ≈ 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.
