On page 10149, a simple and mass‐scalable method, ultrafiltration, is proposed for achieving high‐conductivity poly(3,4‐ethylenedioxythiophene) (PEDOT): poly(4‐styrenesulfonate) (PEDOT:PSS) by Y.‐Y. Noh, J.‐H. Kim, and co‐workers. By effectively removing excess PSS and various reaction impurities using repeated 100 nm‐poremembrane filtration, the purified PEDOT:PSS shows impressive conductivity and sheet resistance as high as 2000 S cm −1 and 37.8 ± 4.5 Ω□ −1 , respectively.
