Abstract
The present invention relates to a method for transferring two-dimensional nanomaterials. The method comprises: (S1) providing a first substrate with a two-dimensional nanomaterial layer on a surface of the first substrate and a carbon nanotube composite film comprising a carbon nanotube film structure and a nanomaterial layer stacked with each other; (S2) covering the two-dimensional nanomaterial layer with the carbon nanotube composite film, wherein the carbon nanotube film structure of the carbon nanotube composite film is in contact with the two-dimensional nanomaterial layer; (S3) obtaining a composite structure comprising the two-dimensional nanomaterial layer and the carbon nanotube composite film by removing the first substrate with a corrosion solution; (S4) placing the composite structure on a surface of a cleaning solution for cleaning; (S5) picking up the composite structure from the cleaning solution by contacting the target substrate with the two-dimensional nanomaterial layer; and (S6) removing the carbon nanotube composite film.
