Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201304611-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Crystalline poly(3, 4‐ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) nanofibrils</bold> with an electrical conductivity of 4380 S cm^‐1 are formed via a solution process using H₂SO₄. 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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg5503z9kh" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
