    摘要: Optical constructions are disclosed. A disclosed optical construction includes first and second optical layers having first and second major surfaces that face each other and are separated by an air gap. The first and second surfaces are susceptible to physically contacting each other at a location in the air gap. The optical construction further includes an optical film that is disposed at the location to prevent the first and second major surfaces from contacting each other at the location. The optical film has an effective index of refraction that is not greater than about 1.3.

    摘要: A process and apparatus for producing a gradient nanovoided article, a gradient nanovoided coating, and a gradient low refractive index coating is described. The process includes providing a first solution of a polymerizable material in a solvent, and providing a first environment proximate a first region of the coating and a different second environment proximate an adjacent region of the coating. The process further includes at least partially polymerizing the polymerizable material to form a composition that includes an insoluble polymer matrix and a second solution. The insoluble polymer matrix includes a plurality of nanovoids that are filled with the second solution, and a major portion of the solvent from the second solution is removed. A first volume fraction of the plurality of nanovoids proximate the first region of the coating is less than a second volume fraction of the plurality of nanovoids proximate an adjacent of the coating. An apparatus for the process is also described, and includes a web line, a coating section, a partial polymerization section, and a solvent removal section.
