  • Patent number: 10899936
    Abstract: Polyurethane-based and epoxy-based coating compositions are described that provide coatings and adhesives that are clear, amphiphobic and durable. Both water and hexadecane readily slide off these surfaces without leaving a residue. Coatings with thicknesses ranging from about 10 nm to about 10 ?m exhibited excellent transmittance properties. Such films exhibited durability against abrasion, ink-resistance, anti-graffiti, anti-fingerprint, and strong adhesion to glass surfaces. The coatings are applicable to electronic devices, fabrics, glass, etc. to prepare optically clear, stain-resistant, and smudge-resistant surfaces.

  • Publication number: 20210002410
    Abstract: The disclosure relates to a thermoset omniphobic composition, which includes a thermoset polymer with first, second, and third backbone segments, first urethane groups linking the first and third backbone segments, and second urethane groups linking the first and second backbone segments. The first, second, and third backbone segments generally correspond to urethane reaction products of polyisocyanate(s), hydroxy-functional hydrophobic polymer(s), and polyol(s), respectively. The thermoset omniphobic composition has favorable omniphobic properties, for example as characterized by water and/or oil contact and/or sliding angles. The thermoset omniphobic composition can be used as a coating on any of a variety of substrates to provide omniphobic properties to a surface of the substrate. Such omniphobic coatings can be scratch-resistant, ink/paint resistant, dirt-repellent, and optically clear.

  • Publication number: 20200398309
    Abstract: The disclosure relates to an omniphobically coated fluid channel including a channel defining an interior channel surface and a flow volume, and a thermoset omniphobic composition as a coating on the interior channel surface. The thermoset omniphobic composition (such as an omniphobic polyurethane or epoxy composition) includes a thermoset polymer with first, second, and third backbone segments. The first, second, and third backbone segments can correspond to urethane or urea reaction products of polyisocyanate(s), amine-functional omniphobic polymer(s), and polyol(s), respectively, for omniphobic polyurethanes. Similarly, the first, second, and third backbone segments can correspond to urea or beta-hydroxy amine reaction products of polyamine(s), isocyanate-functional omniphobic polymer(s), and polyepoxide(s), respectively, for omniphobic epoxies.

  • Publication number: 20200085686
    Abstract: A medication bottle includes an outer container wall, an inner container wall and a fluid, such as an aversive liquid, located between the walls. In another aspect, the fluid is located within separate compartments or channels located between the walls where the walls contact or are secured to each other. A further aspect provides a removeable cap including multiple sensors, at least one of which is a biometric sensor.
