Abstract
Methods of transferring nanostructures from a first substrate to another substrate using a copolymer polymerized from one or more non-crosslinking monomers and one or more comonomers bearing crosslinkable groups as a transfer medium are provided. Relative to a poly(methyl methacrylate) homopolymer, the crosslinkable copolymers bond more strongly to the first substrate and, as a result, are able to transfer even very narrow nanostructures between substrates with high transfer yields.
Claims19
A method for transferring one or more nanostructures from a first substrate to a second substrate, the method comprising:
- applying a coating of a crosslinkable copolymer over one or more nanostructures on a surface of the first substrate, wherein 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.
