  • Patent number: 8758894
    Abstract: A transparent laminate comprises an optically clear, cured coating layer including abrasion-resistant nanoparticles, and one or more monomers and/or one or more oligomers that are reacted in the presence of an ultraviolet light photoinitiator. The coating layer also contains a surface portion rich in hydrophilic surfactant so that the coating layer when residing on a transparent substrate forms a laminate having good abrasion resistant properties as well as good anti-fog properties.

  • Patent number: 6890987
    Abstract: 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.

  • Patent number: 6143358
    Abstract: 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.

  • Patent number: 5897918
    Abstract: 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.
