  • Patent number: 9403992
    Abstract: An exemplary embodiment provides coated polymeric substrates that have a polymeric substrate body with a coated surface. The surface coating includes more than one pair of coating layers. Each pair of coating layers includes a first applied coating layer and a second applied coating layer. In addition, an indicator, applied on top of or between coating layers, provides an indication of wear of the coating. The first and second applied coating layers have a thickness between about 3 to about 10 nanometers. The coating exhibits a Hall-Petch effect.

  • Patent number: 8962753
    Abstract: A hybrid coating composition including an organosilane component, a metal alkoxide component and a surfactant component, with the metal alkoxide component present in the composition at a molar ratio of about 75:1 with respect to the surfactant component. The hybrid coating composition once cured on a transparent substrate has an initial clarity greater than 98. Transparent members are also disclosed that include a transparent substrate having the hybrid coating composition cured on a first major surface thereof.

  • Patent number: 8932737
    Abstract: A coating and associated method for coating is disclosed. The coating provides a hard, transparent, UV blocking coating for a substrate. A UV blocking layer is first deposited upon the substrate, and a hard coating is deposited above the UV blocking layer. A soft coating layer may be deposited between the UV blocking layer and the hard coating. The soft and hard coating layers may both have the general composition SiOxCy. the soft and hard coating layers may be deposited by a plasma vapor deposition process.

  • Patent number: 8709545
    Abstract: A hybrid coating including a mixture of an organosilane component, a metal alkoxide component and a surfactant component. A method for coating a substrate including cleaning a substrate surface, treating the surface with oxygen plasma, applying an adhesion promoter to the surface, then applying a hybrid coating to the surface and curing the hybrid coating. A method for making a hybrid coating includes preparing a mixture comprising an organosilane, a metal alkoxide and a surfactant, heating the mixture; and filtering the mixture.
