  • Publication number: 20240110068
    Abstract: A thin oil film having parylene irregular dendritic-like columns extending from one side to another exhibits hydrophobic properties that can be used as a corrosion resistant coating or water-repellant, biofouling resistant surface. This parylene-in-oil layer can be paired with an adjacent layer of solid parylene that it overlays or underlays. The solid parylene cross polymerizes with the parylene dendrites, keeping them in place as well as the oil film. The parylene dendrites are fabricated by chemical vapor deposition (CVD) of parylene over the oil layer, the dendrites self-forming from the bottom to the top. Continued CVD over the dendrites can produce a top layer of solid parylene. Etching the solid parylene away can result in a water repellant, anti-biofouling surface.
