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.
Claims12
A process for producing a hydrophobic coating on a substrate, wherein the process comprises at least one electrochemical deposition technique comprising:
- forming an aqueous solution comprising at least one positively-charged metal-based agent and at least one type of surface-modified inorganic particles dispersed in the solution, wherein the surface-modified inorganic particles comprise a plurality of nanopores;
- positioning the substrate in the solution;
- and
- electrochemically depositing a two-phase hydrophobic coating comprising a first phase and a second phase, wherein the first phase comprises a metal based matrix comprising a single metallic element or metallic compound formed from the at least one positively-charged metal-based agent, and wherein the second phase comprises the at least one type of surface-modified inorganic particles, and wherein the first phase is separated from the second phase.
