Abstract
The invention relates to a method for transferring a two-dimensional nanometer material by using a carbon nano-tube film. The method comprises: covering the surface of a substrate with a carbon nano-tube composite film, wherein the surface of the substrate forms a two-dimensional nanometer material; forming a two-dimensional nanometer material / carbon nano-tube composite film composite structure after removing the substrate; transferring the two-dimensional nanometer material / carbon nano-tube composite film composite structure to the surface of a target substrate; and finally removing the carbon nano-tube composite film to achieve the transferring of the two-dimensional nanometer material. Compared with the method in the prior art, the method of the present invention is clean, and cannot introduce other impurities, and the transferred two-dimensional nanometer material has almost no damage and high integrity.
Description
technical field [0001] The invention relates to a method for transferring two-dimensional nanometer materials, in particular to a method for transferring two-dimensional nanometer materials by using a carbon nanotube composite film. Background technique [0002] Two-dimensional nanomaterials such as graphene, boron nitride, and molybdenum disulfide have become research hotspots in chemistry, materials science, and physics due to their excellent properties. Scale-up preparation and transfer are still the focus of 2D nanomaterials research. At present, the most common method for transferring two-dimensional nanomaterials from substrates such as copper is to use polymethyl methacrylate (PMMA) or thermal release tape as a transfer medium, and after etching copper, the two-dimensional nanomaterials and the transfer medium Transfer to the target substrate and finally remove the transfer medium. However, in actual operation, PMMA or thermal release tape is not easy to remove, and...
