  • Transfer of nanostructures using crosslinkable copolymer films
    Patent number: 12077438
    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.
    Type: Grant
    Filed: March 23, 2021
    Date of Patent: September 3, 2024
    Assignee: Wisconsin Alumni Research Foundation

  • SELECTED-AREA DEPOSITION OF HIGHLY ALIGNED CARBON NANOTUBE FILMS USING CHEMICALLY AND TOPOGRAPHICALLY PATTERNED SUBSTRATES
    Publication number: 20220255001
    Abstract: Methods for forming films of aligned carbon nanotubes are provided. Also provided are the films formed by the methods and electronic devices that incorporate the films as active layers. The films are formed by flowing a suspension of carbon nanotubes over a substrate surface that is chemically and topographically patterned. The methods provide a rapid and scalable means of forming films of densely packed and aligned carbon nanotubes over large surface areas.
