The hybrid composites which consist of PEDOT:PSS/graphene oxides and PEDOT:PSS/reduced graphene oxide, were successfully constructed on Au microelectrodes. The graphene oxide was synthesized by using modified Hummer’s methods. The PEDOT:PSS/(r)GO composites were coated by electrochemical chronopotentiometry methods. The cyclic voltammetry test, biphasic electrical stimulation, electrochemical impedance spectroscopy, and durability test were performed to evaluate the stimulating efficiencies for the neural micro-electrodes. The electrochemical performances were also compared by varying the degree of reduction of GOs. Overall, PEDOT:PSS/(r)GOs composites were significantly better than the PEDOT:PSS in terms of electrochemical charge transports as well as charge injection durability.
