Abstract
AbstractOver the last few years, graphene oxide (GO) has stood out as an ideal carbon‐filler to dope polymer matrix, specifically conductive polymers. This paper investigates the possibility of producing ternary nanocomposites based on a conductive polymer poly(3,4 ethylene dioxythiophene) polystyrene sulfonate (PEDOT:PSS), doped with graphene oxide (GO) and is additivated with a green dispersing and reducing agent (ascorbic acid). Three‐component inks have been developed and their rheological and surface tension properties are studied to evaluate their filmability. Subsequently, through the drop‐casting technique, thin films of the inks are produced, and their electrochemical behavior is deeply analyzed via cyclic voltammetry tests (CV). Particularly, PEDOT:PSS/GO/AA ink shows a higher specific capacitance (Csp) up to 29.84 mF cm−2 than pristine PEDOT:PSS, suggesting that this ink can be used as an electrode material for supercapacitor devices.
