▎ 摘　　要

NOVELTY - A graphene-poly (3,4- ethylenedioxythiophene) co-extruded film manufacturing method involves laminating a graphene oxide layer on a substrate. The laminated graphene oxide layer is reduced to a graphene layer and a poly (3,4- ethylenedioxythiophene) layer is laminated on the graphene layer. USE - Method for manufacturing a graphene-poly (3,4- ethylenedioxythiophene) co-extruded film. ADVANTAGE - The method enables improving mechanical surface property of the graphene-poly (3,4- ethylenedioxythiophene) co-extruded film by the graphene layer that is laminated inside the film while maintaining permeability of the graphene-poly (3,4- ethylenedioxythiophene) co-extruded film. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene-poly (3,4- ethylenedioxythiophene) co-extruded film comprising a poly (3,4- ethylenedioxythiophene) layer (2) a method for manufacturing a freestanding graphene-poly (3,4- ethylenedioxythiophene) co-extruded film (3) a freestanding graphene-poly (3,4- ethylenedioxythiophene) co-extruded film. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for manufacturing a graphene-poly (3,4- ethylenedioxythiophene) co-extruded film.'(Drawing includes non-English language text)'
