摘要：

Crystalline poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) nanofibrils with an electrical conductivity of 4380 S cm -1 are formed via a solution process using H2SO 4. The concentrated H2SO4 treatment induces a significant structural rearrangement of the PEDOT:PSS via a charge-separated transition mechanism, resulting in highly ordered and densely packed PEDOT:PSS nanofibrils. The PEDOT:PSS electrode shows a sheet resistance of 46 Ω sq-1 with 90% optical transmittance. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
