Abstract:
Graphene is an ideal material for the preparation of high performance conductive film because of its unique electrical properties, excellent mechanical ductility and good chemical stability. This paper presents the preparation of a double-layered graphene/poly(3, 4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) conductive film, in which the PEDOT:PSS film was fabricated by using spray-coating technique. The surface morphology, optical and electrical properties of the double-layered conductive films were investigated. PEDOT:PSS can not only reduce the surface resistance of the graphene films, but also smooth the film surface. Flexible organic light-emitting diodes based on the double-layered film were fabricated, and the current efficiency increased with the voltage and reached its maximum of 0.9 cd/A when the voltage was 12 V. The device luminance did not show obvious degradation after 100 times bending with a radius of curvature of 10 mm. The hybrid films hold promise for the practical application of FOLEDs.
