METHOD FOR PRODUCING COMPOSITE FILM COMPRISING GRAPHENE AND CARBON NANOTUBES

摘要

[Problem] To provide a method for producing a composite film that enables a composite film having a structure obtained by alternately laminating graphene and carbon nanotubes to be efficiently and easily produced. [Solution] This method for producing a composite film provided with a structure obtained by alternately laminating a nanosheet structure (10) and a nano carbon structure (12) is characterized by being provided with: a. a step in which the nano carbon structure (12) is cationically functionalized; b. a step in which a dispersion liquid of the functionalized non carbon structure (12) and a dispersion liquid of the nanosheet structure (10) is mixed to produce a suspension containing the nano carbon and nanosheet structures; and c. a step in which the dispersion medium is removed from the suspension to produce a film.
