Abstract

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.
