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