  • Publication number: 20190177233
    Abstract: This invention relates generally to an article that includes a base substrate, an intermediate layer including at least one element or compound selected from titanium, chromium, indium, zirconium, tungsten, and titanium nitride on the base substrate, and a hydrophobic coating on the base substrate, wherein the hydrophobic coating includes a rare earth element material (e.g., a rare earth oxide, a rare earth carbide, a rare earth nitride, a rare earth fluoride, and/or a rare earth boride). An exposed surface of the hydrophobic coating has a dynamic contact angle with water of at least about 90 degrees. A method of manufacturing the article includes providing the base substrate and forming an intermediate layer coating on the base substrate (e.g., through sintering or sputtering) and then forming a hydrophobic coating on the intermediate layer (e.g., through sintering or sputtering).

  • Publication number: 20180161836
    Abstract: The articles and methods described herein provide a way to manipulate condensation on a surface by micro/nano-engineering textures on the surface and filling the spaces between the texture features with an impregnating liquid that is stably held therebetween or therewithin. The articles and methods allow droplets of water, or other condensed phases, even in micrometer size range, to easily shed from the surface, thereby enhancing contact between a condensing species and the condensing surface. It has been found that dropwise condensation is enhanced by the use of an impregnating (secondary) liquid that has a relatively high surface tension, and, even more preferably, an impregnating liquid that has both a high surface tension and a low viscosity.

  • Publication number: 20160333187
    Abstract: Embodiments described herein relate generally to a system and methods for controlling and/or modifying the degradation behavior of degradable materials via a surface treatment and/or coating. This surface treatment and/or coating (also referred to herein as a “barrier”) can be used to modify the degradation profile without changing the bulk of the degradable material. The system includes a substrate that includes a degradable material and barrier configured to protect the substrate from a foreign environment. The barrier can include a conformal coating and/or a liquid impregnated surface engineered specifically to tailor the degradation profile of the underlying substrate. Optionally, a trigger mechanism can be used to further control and/or modify the degradation behavior of the substrate.
