Graphene -gold electrodes for flexible nanogenerators based on porous piezoelectric PVDF Films
In this work, we develop graphene-gold electrodes (GGEs) for flexible nanogenerators made of porous piezoelectric PVDF films. The bilayer electrode structure was conceived in order to avoid the short circuit between top and bottom electrodes produced through direct Au sputtering over the film surface. Gold was sputtered over chemical-vapor- deposition (CVD) grown graphene film, that was subsequently transferred onto a PVDF film.
