A METHOD FOR MANUFACTURING GRAPHENE-PEDOT COMPOSITE FILMS AND FREE-STANDING GRAPHENE-PEDOT COMPOSITE FILMS, AND GRAPHENE-PEDOT COMPOSITE FILMS AND FREE-STANDING GRAPHENE-PEDOT COMPOSITE FILMS MANUFACTURED BY THE SAME

摘要

Provided are a graphene-PEDOT composite film and a freestanding graphene-PEDOT composite film manufacturing method, and a graphene-PEDOT composite film and a freestanding graphene-PEDOT composite film produced thereby. Graphene-PEDOT composite film production method according to the present invention comprises the steps of laminating a graphene oxide layer on a substrate; Reducing the stacked graphene oxide layer to prepare a graphene layer; And laminating a poly (3,4-ethylenedioxythiophene) (PEDOT) layer on the graphene layer, wherein the graphene-PEDOT composite film according to the present invention maintains the permeability of the PEDOT film therein. The laminated graphene layer has improved electrical, mechanical and surface properties. In addition, according to the composite film production method of the present invention, it is possible to manufacture a nanometer-scale freestanding PEDOT film.
