Disclosed are perfluoropolyether silicon compounds, coatings containing the perfluoropolyether silicon compounds, methods of making the perfluoropolyether silicon compounds, and methods of making perfluoropolyether silicon coatings.

Fluorinated organic silicon coating material

Disclosed are substrates with a first hydrophobic layer having a first contact angle and a second hydrophobic layer having a second contact angle, the first hydrophobic layer between the second hydrophobic layer and the substrate, the first contact angle being greater than the second contact angle.

Nano structured phased hydrophobic layers on substrates

Invisible logos may be made by forming a hydrophilic coating and a hydrophobic coating on a substrate surface, so that a portion of the hydrophilic coating and a portion of the hydrophobic coating are exposed. The invisible logos are undetectable to the human eye, but may be temporarily viewed in response to stimuli.

Making invisible logos using hydrophobic and hydrophilic coatings

A solid composition having a solid state film forming substance mixed with an inert carrier. The composition is heated in a vacuum chamber to evaporate the film forming substance by sublimation to form a molecular beam of amphiphilic molecules which settle on a substrate surface within the chamber and bond thereto while self-assembling into a thin film.

Product for vapor deposition of films of amphiphilic molecules or polymers

The invention relates to a composite containing a porous carrier and an amphiphilic material. The composite may be employed in methods and systems for forming thin films on substrates.

Composition with film forming alkylsilsesquioxane polymer and method for applying hydrophobic films to surfaces

A magnesium fluoride surface having a thin film of amphiphilic molecules bonded thereto by way of a primer film of a metal oxide having a surface that hydrolyzes on exposure to airborne moisture. The amphiphilic molecules are chemically bonded to hydroxy groups on the hydrolyzed surface of the metal oxide primer film.

Hydrophobic thin films on magnesium fluoride surfaces

A rupturable container that contains vaporizable amphiphilic molecules for use in forming films on substrates. The container is ruptured to release the amphiphilic molecules which are vaporized by heat and allowed to settle on a substrate.

Rupturable container of amphiphilic molecules

A substrate surface is coated with a thin film by exposing the substrate to a vapor of amphiphilic molecules in a vacuum chamber, and allowing the amphiphilic molecules to spontaneously self-assemble and attach to the substrate surface wherein the substrate and a quantity of a vaporizable film forming material containing amphiphilic molecules is placed in a vacuum chamber, establishing a vacuum within said chamber, followed by vaporization of the film forming material.

Method for modifying surfaces with ultra thin films

A faster and more efficient method for applying ultra thin films to substrate surfaces is disclosed. The method comprises heating a film forming composition comprising amphiphilic molecules to a liquid state, immersing the substrate surface in the heated liquid composition to heat the surface, and washing away the excess composition. For surfaces that ordinarily have insufficient or no chemical moieties reactive with the amphiphilic molecules, the immersion in the heated composition causes the substrate to become porous and expose previously unavailable chemically reactive moieties in the surface matrix. The amphiphilic molecules then self-assemble, chemically bond to the surface matrix and self-polymerize with each other and with other surface matrix-bound and/or surface-bound molecules to form the ultra thin surface film. The method is also faster and more efficient for coating non porous and metal surfaces.
