Development of transparent conducting films composed of graphene/silver nanowire/polymer stacked layers

Abstract

Transparent conducting films with a low resistance, high transparency, high flexibility, light weight and low cost are required for optical device applications. Graphene and silver nanowires have been expected to replace conventional indium-tin oxide films. Graphenes, however, have the disadvantage of high electric resistance, and silver nanowires have the issues of roughness, chemical instability and difficulty with energy-level control. The authors have found that graphene/silver nanowire/polymer stacked layers overcome these disadvantages.
