This work describes a ternary screen-printed electrode system, composed of aqueous poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonic acid) (PEDOT:PSS), graphene, and hydrous ruthenium (IV) oxide (RuO2) nanoparticles for use in high-performance electrochemical capacitors. As a polymeric binder, PSS allows stable dispersion of graphene and hydrous RuO2 NPs in an aqueous PEDOT:PSS system through electrostatic stabilization, ensuring better utilization of the three components. The effects of graphene and hydrous RuO2 NPs on the electrical and electrochemical properties of PEDOT:PSS were systematically investigated. |
