A highly conductive, air stable and scalable poly(3,4‐ethylenedioxythiophene) (PEDOT): poly(4‐styrenesulfonate) (PEDOT:PSS) are prepared by using mass production ultrafiltration. By effectively removing excess PSS and various reaction impurities using repeated 100 nm pore membrane filtration, purified PEDOT:PSS exhibit conductivity as high as 2000 S cm −1 .
