Poly(3,4-ethylenedioxythiophene) mixed with poly (styrenesulfonate) (PEDOT:PSS) is considered as one of the most valuable conductive polymers due to its high conductivity, transparency and mechanical flexibility. Many experiments have proved that H2SO4 post-treatment is an effective way to enhance the electrical conductivity of PEDOT:PSS films. Here we reported a method for the fabrication of PEDOT:PSS films with conductivity as high as 6323.9 ±364.5 S/cm, based on a two-step H2SO4 post-treatment. This very high conductivity is, as far as we know, the highest reported value for PEDOT:PSS films by solution preparation. The removal of PSS and redox reaction are the keys to enhance the conductivity of PEDOT: PSS films.
