Abstract Scope |
Conductive polymers have garnered extensive attention due to their excellent mechanical flexibility for wearable electronics. Particularly, PEDOT:PSS has been widely investigated, and now its electrical conductivity as a thin-film (2D) has been reported as high as Indium tin oxide. However, the research on PEDOT:PSS as a fiber (1D) has not been conducted. Herein, we will present the direct-writing method of PEDOT:PSS on top of the graphene layer, in which PEDOT:PSS-nanofiber/graphene becomes flexible and transparent nanoelectrodes. First, a transferred CVD-grown graphene layer on an insulating substrate serves as a ground layer for the droplet-jet mode near-field electrospinning. The printed PEDOT:PSS-nanofiber, then, serves as a mask layer during the plasma etching process for the graphene region underneath it. As a result, the graphene/PEDOT:PSS-nanofiber composite, the same as the printed fiber pattern, is remained as nanoelectrodes. Electrical, optical, and mechanical properties of the composite will be investigated and discussed in the presentation. |
