  • Methods of making hydrophobic contoured surfaces and hydrophobic contoured surfaces and devices made therefrom
    Patent number: 11000975
    Abstract: A method of creating a polymer surface with surface structures is disclosed. The method includes creating a mold, forming a metal sheet into the molds, creating a surface structure on a surface of the metal sheet by exposing the surface to laser pulses, and bringing a curable polymer to be in contact with the surface of the metal sheet containing the surface structure, curing the curable polymer, and separating the cured polymer from the metal sheet, resulting in a polymer surface containing the surface structure. The polymer surfaces with the surface structures can be hydrophobic or superhydrophobic depending on the micro and nano features contained by the surface structures.
    Type: Grant

    Date of Patent: May 11, 2021
    Assignee: Purdue Research Foundation
    Inventors: Yung C Shin, Shashank Sarbada
