▎ 摘  要

NOVELTY - Method for transferring one or more nanostructures from a first substrate to a second substrate, comprises: applying a coating of a crosslinkable copolymer over one or more nanostructures on a surface of the first substrate, where the crosslinkable copolymer is polymerized from one or more non-crosslinking monomers and one or more comonomers bearing crosslinkable groups; heating the crosslinkable copolymer to induce crosslinking of the crosslinkable copolymer and to form bonds between the crosslinkable copolymer and the surface of the first substrate; releasing the one or more nanostructures and the crosslinked copolymer from the first substrate; transferring the one or more nanostructures and the crosslinked copolymer onto a surface of the second substrate; and removing the crosslinked copolymer from the one or more nanostructures. USE - Method for transferring one or more nanostructures from a first substrate to a second substrate. ADVANTAGE - The method works well for graphene nanoribbons having larger widths, and is suitable for transfer of very narrow nanoribbons.
