Poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a conductive polymer, have attracted attention as promising materials for future electronic applications, owing to its tunable doping level for high electrical conductivity (σ) through simple post‐treatments. A novel post‐treatment...
