Organic transparent conductors (OTCs), which are processable from solution but possess nearly comparable electrical conductivity (σdc) with indium tin oxide (ITO), have been explored for use in flexible and printable electronic devices. However, many OTCs suffer from a low σdc that arises from the non-crystalline feature inherent in organic-based materials. Therefore, the formation of a well-ordered crystalline structure in organic conductors is a key requirement for the development of highly conductive, flexible, and transparent electrodes. Herein, we demonstrate that a solution process using sulfuric acid (H2SO4) with a well-known conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(4-styrenesulfonate) (PSS), induced a high degree of crystalline nanofibrils with σdc » 4,380 S/cm, which corresponds to the highest value for this system and is nearly comparable to that of ITO. |
