Highly Conductive All‐Plastic Electrodes Fabricated Using a Novel Chemically Controlled Transfer‐Printing Method. (23rd February 2015) - Kim, Nara
Abstract A novel transfer‐printing method for high‐performance all‐plastic transparent electrodes is demonstrated. A solution process using H2SO4 not only dramatically enhances the electrical conductivity of poly(3, 4‐ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) over 4000 S cm−1 but also chemically modifies its adhesion properties, thereby enabling expeditious "pick‐and‐place" transfer onto arbitrary surfaces using elastomeric stamps. Flexible and transparent optoelectronic devices with transferred PEDOT:PSS electrodes show superb performances.
