  • Membrane surface hydrophobicity through electro-hydrodynamic film patterning
    Patent number: 10889030
    Abstract: A method of creating a hydrophobic polymer membrane surface includes depositing a polymer material onto a heated carrier, using the heated carrier, transporting the polymer material past an electrode field generator, generating an electric field adjacent the carrier, using the electric field to form a pattern in the polymer material to form a patterned polymer membrane, rinsing the patterned polymer membrane in a first bath, and setting the pattern into the patterned polymer membrane in a second bath.
    Type: Grant
    Filed: June 8, 2020
    Date of Patent: January 12, 2021
    Assignee: PALO ALTO RESEARCH CENTER INCORPORATED
    Inventors: Charles-Francois de Lannoy, Corie Lynn Cobb

  • Membrane surface hydrophobicity through electro-hydrodynamic film patterning
    Patent number: 10710283
    Abstract: A roll-to-roll system for forming a hydrophobic polymer membrane surface includes a heated carrier belt, a repository of polymer material arranged to deposit the polymer material onto the carrier to create a heated polymer, an electrode belt positioned opposite the carrier belt, an electric field generator positioned to generate an electric field between the carrier belt and the electrode belt and to infuse a pattern into the heated polymer to form a patterned polymer film, and a solvent bath to rinse the patterned polymer film. A method of creating a hydrophobic polymer membrane surface includes depositing a polymer material onto a heated carrier, using the carrier, transporting the polymer material past an electrode that acts as an electric field generator, generating an electric field adjacent the carrier, using the electric field to infuse a pattern into the polymer membrane surface, and setting the pattern into the polymer membrane surface.
