Abstract
Provided herein are multilayer structures comprising superhydrophobic coatings, methods of making, and methods of using. Also set forth herein are improved adhesives with include PTFE or other fluoropolymers as a superhydrophobic surface. Also set forth herein are improved adhesives with can be applied as a paint to a surface. These superhydrophobic surfaces are useful for a variety of applications, including, but not limited to, drag reduction, as an anti-fouling surface in marine engineering, and as sealants and gaskets in static applications.
Claims53
A composite structure comprising a substrate and a coating disposed on a surface of the substrate,
- wherein the coating comprises a layer comprising an amine-functionalized polymer having a uniform thickness of between about 1 μm to about 500 μm and a layer comprising a fluoropolymer, a poly(olefin), or a combination thereof;
- and
- wherein the hydrophobic coating is in contact with an aqueous environment/media.
A method of making a composite structure, comprising:
- a. applying amine-functionalized polymer layer to a fluoropolymer and/or a poly(olefin) to form a coating;
- and
- b. applying the coating to a surface of a substrate to form a composite.
A method of making a composite structure, comprising:
- a. applying an amine-functionalized polymer layer to a surface of a substrate;
- and
- b. applying a fluoropolymer or a poly(olefin) to the amine-functionalized polymer layer.
A method of making a composite structure, comprising applying a combination of an amine-functionalized polymer and a fluoropolymer and/or a poly(olefin) to a surface of a substrate.
A method of making a composite structure, comprising:
- a. applying an amine-functionalized polymer layer to a surface of a substrate;
- and
- b. applying a paint coating to the amine-functionalized polymer layer.
A method of making a composite structure, comprising:
- a. applying an amine-functionalized polymer layer to a surface of a substrate;
- b. applying amine-functionalized polymer layer to a fluoropolymer, a poly(olefin), or a combination thereof, to form a coating;
- and
- b. joining the amine-functionalized polymer layers to form a composite.
