  • Publication number: 20230295827
    Abstract: Articles comprising a substrate and a coating are described. In some examples, the coating is disposed on at least one region of the surface and comprises at least one hydrophobic layer. In some instances, the hydrophobic layer comprises a composite comprising a single metallic element or metallic compound and at least one type of surface-modified inorganic particles to provide a metal-based matrix. In certain examples, the at least one type of surface-modified inorganic particles within the metal-based matrix is embedded within the metal-based matrix and is separate from the single metallic element or metallic compound in the metal-based matrix. Processes for producing the coatings and articles are also described.

  • Publication number: 20210309870
    Abstract: A method is provided for creating a porous coating on a surface of a substrate by electrodeposition. The substrate is a part of the cathode. An anode is also provided. A coating is deposited or disposed on the surface by applying a voltage that creates a plurality of porous structures on the surface to be coated. Continuing to apply a voltage creates additional porosity and causes portions of the attached porous structures to detach. A covering layer is created by applying a voltage that creates a thin layer that covers the attached porous structures and the detached portions which binds the porous structures and detached portions together.
