The potential cycling stability is compared for poly(3,4‐ethylenedioxythiophene) (PEDOT) composite films prepared either with graphene oxide (GO), reduced GO (RGO) or poly(styrenesulfonate) (PSS). It is shown that PEDOT‐GO had reversible redox behavior and fast charging/discharging with at least equal electrochemical properties to PEDOT‐PSS. 10 000 potential cycles between −0.5–0.5 V in the three‐electrode cell decreased the anodic charge of PEDOT‐GO with 6.2 %. In the two‐electrode cell, the decrease was only 5.4 % between 0–0.7 V. The potential cycling stability of PEDOT‐GO and PEDOT‐RGO prepared electrochemically without other additives than GO has not been previously reported.
