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 H2SO4. The concentrated H2SO4 treatment induces significant structural rearrangement the PEDOT:PSS charge-separated transition mechanism, resulting in highly ordered and densely packed nanofibrils. electrode shows sheet resistance 46 Ω sq-1 90% optical transmittance.
