Abstract

Poly(3,4-ethylenedioxythiophene) (PEDOT)-based thin film has relatively high conductivity, flexibility and transmittance. However, the improvement for mechanical strength and enhanced conductivity is still required to be adapted for commerical applications. Graphene, a one-atom-thick planar sheet of sp²-bonded carbon atoms is considered as an ideal nanocomposite material for these purposes. In this study, we have developed a PEDOT and graphene composite films, two layered graphene/PEDOT and three layered graphene/PEDOT/graphene, by using a layer-by-layer method.
