摘要： 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.

摘要： 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.

摘要： The present invention relates to a transmission electron microscope (TEM) micro-grid and a method for preparing the TEM micro-grid. The TEM micro-grid comprises a porous silicon nitride substrate and a graphene layer located on a surface of the porous silicon nitride substrate. The porous silicon nitride substrate comprises a plurality of through holes. The graphene layer covers the plurality of through holes. The method for preparing the TEM micro-grid provided in the present disclosure uses a carbon nanotube film structure to transfer a graphene layer to a surface of a porous silicon nitride substrate.
