  • Patent number: 11008658
    Abstract: A method for preparing a nanowire or nanorod on a patterned monolayer or thin film supported by a 2D material substrate in a nonpolar environment comprises the steps of: functionalizing a supporting 2D material substrate using a patterned monolayer or thin film of a polymerized amphiphiles comprising both hydrophobic and hydrophilic constituents; and then growing a nanowire or nanorod on the functionalized supporting 2D material substrate in a salt solution or suspension, wherein the patterned monolayer or thin film comprises a polymerizable phospholipid with a terminal amine. A gold nanowire or nanorod so prepared has a highly controlled diameter of about 2 nm, and a length of about 100 nm, dependent in part on molecular domain sizes in the monolayer.

  • Publication number: 20210060604
    Abstract: The present invention generally relates to a device and a process for performing large-scale noncovalent functionalization of 2D materials, with chemical pattern elements as small as a few nanometers, using thermally controlled rotary Langmuir-Schaefer conversion. In particular, the present invention discloses a device comprising a thermally regulated disc driven by a rotor with fine speed control configured to be operable with a Langmuir trough for performing large-scale noncovalent functionalization of 2D materials, achieving ordered domain areas up to nearly 10,000 ?m2, with chemical pattern elements as small as a few nanometers. A process using the device for performing large-scale noncovalent functionalization of 2D materials with chemical pattern elements as small as a few nanometers is within the scope of this disclosure.

  • Patent number: 10889669
    Abstract: This invention generally relates to a method for modulating interfacial wettability of a noncovalent nanoscopic monolayer or thin film. Particularly, this invention relates to a method for modulating interfacial wettability of a two-dimensional (2D) material using a molecular layer prepared from a polymerizable amphiphilic monomer having a hydrophilic head and a hydrophobic tail, wherein enhanced or decreased wettability of said 2D material is achieved by proper allocating the position of polymerizable group relative to the hydrophilic head and the hydrophobic tail.

  • Publication number: 20200402799
    Abstract: The present invention generally relates to a method for preparing structurally unique nanomaterials and the products thereof. In particular, the present invention discloses a method for preparing an array of ultra-narrow nanowire or nanorod on a patterned monolayer supported by a 2D material substrate in a controlled environment, wherein said pattered monolayer comprises a polymerizable amphiphiles such as phospholipid with a terminal amine and wherein said controlled environment comprises a major nonpolar solvent, a trace amount of polar solvent, and a unsaturated aliphatic amine. Gold nanowires (AuNWs) so prepared have a highly controlled diameter of about 2 nm, a length up to about 1000 nm, and an AuNW ordering over an area >100 ?m2.

  • Publication number: 20200299542
    Abstract: The present invention generally relates to a method for creating a chemically structured surface with structural elements as small as 1 nm, on a material that does not itself display a high degree of ordering, using thin molecular layers that minimize the material added through the coating. In particular, the present invention discloses a method for assembling a chemical pattern on a surface, comprising pattern elements with scales that can be as small as 1 nm, and then transferring that pattern to another substrate, on which the pattern would not form natively. In the described method, the patterned monolayer is comprised of polymerizable amphiphiles such as diyne phospholipids or diynoic acids, which are transferred from the ordering substrate using a transferring material such as poly(dimethylsiloxane).

  • Publication number: 20200061667
    Abstract: This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a ‘sitting’ phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a ˜6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.
