Patent number: 11666941Abstract: 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.Type: GrantFiled: October 28, 2019Date of Patent: June 6, 2023Assignee: Purdue Research FoundationInventors: Shelley A Claridge, Shi Wah Choong, Jae Jin Bang, Shane Richard Russell

Patent number: 11193042Abstract: 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).Type: GrantFiled: March 17, 2020Date of Patent: December 7, 2021Assignee: Purdue Research FoundationInventors: Shelley A. Claridge, Tyson C. Davis

Patent number: 11008658Abstract: 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.Type: GrantFiled: February 28, 2019Date of Patent: May 18, 2021Assignee: Purdue Research FoundationInventors: Shelley A.
