Abstract
Articles comprising a substrate, a first layer comprising polymeric material with nanoparticles protruding from a major surface thereof, and away from the substrate, and a second layer having major surface is a first nanostructured. Embodiments of the articles are useful for display applications (e.g., liquid crystal displays (LCD), light emitting diode (LED) displays, or plasma displays); light extraction; electromagnetic interference (EMI) shielding, ophthalmic lenses; face shielding lenses or films; window films; antireflection for construction applications; and, construction applications or traffic signs.
Claims10
An article comprising:
- a substrate having first and second, generally opposed, major surfaces;
- a first layer having first and second generally opposed major surfaces, wherein the first layer comprises polymeric material with nanoparticles protruding from the second major surface thereof and away from the first major surface of the substrate, and wherein the first layer, without taking into account the protruding nanoparticles, has an average thickness in a range from 50 nanometers to 150 nanometers;
- and
- a second layer having first and second major surfaces, wherein the first major surface of the second layer is on the second major surface of the first layer, and wherein the second major surface is a first nanostructured surface.
