“…AAGO-PEDOT thin films also show well-defined square edges and a uniform black-coloured surface, but some residual ink droplets are also visible. Standard PEDOT:PSS was printed for comparison ( Figure 7 e), showing uniform printed shape, and similar results have been obtained by the same authors with other PEDOT:PSS-based solutions [ 30 , 33 ]. However, a higher print speed equal to 25 mm/s is used for this study, which is much higher than the one used in multiple studies, that is, 1 mm/s [ 60 , 61 ].…”

Among conductive polymers, poly(3,4 ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) has been widely used as an electrode material for supercapacitors, solar cells, sensors, etc. Although PEDOT:PSS-based thin films have acceptable properties such as good capacitive and electrical behaviour and biocompatibility, there are still several challenges to be overcome in their use as an electrode material for supercapacitors. For this reason, the aim of this work is to fabricate and characterise ternary nanocomposites based on PEDOT:PSS and graphene oxide (GO), blended with green additives (glucose (G) or ascorbic acid (AA)), which have the benefits of being environmentally friendly, economical, and easy to use. The GO reduction process was first accurately investigated and demonstrated by UV-Vis and XRD measurements. Three-component inks have been developed, and their morphological, rheological, and surface tension properties were evaluated, showing their printability by means of Aerosol Jet® Printing (AJ®P), an innovative direct writing technique belonging to the Additive Manufacturing (AM) for printed electronics applications. Thin films of the ternary nanocomposites were produced by drop casting and spin coating techniques, and their capacitive behaviour and chemical structures were evaluated through Cyclic Voltammetry (CV) tests and FT-IR analyses. CV tests show an increment in the specific capacitance of AAGO-PEDOT up to 31.4 F/g and excellent overtime stability compared with pristine PEDOT:PSS, suggesting that this ink can be used to fabricate supercapacitors in printed (bio)-electronics. The inks were finally printed by AJ®P as thin films (10 layers, 8 × 8 mm) and chemically analysed by FT-IR, demonstrating that all components of the formulation were successfully aerosolised and deposited on the substrate.

“…In this work, the use of a commercial GO, rather than waste materials (ash) [ 30 ], represents a starting point for the sensible bio-electronic application. However, without excluding the possibility of exploring in the future waste products that must guarantee appropriate properties.…”

Over 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.
