Abstract
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. 10000 potential cycles between -0.5-0.5V 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 0-0.7V. The potential cycling stability of PEDOT-GO and PEDOT-RGO prepared electrochemically without other additives than GO has not been previously reported.
