[0097] Figure 8 is a flowchart of an exemplary method of making an article according to the present application. see Figure 8 , the method for making an article includes obtaining a first material 810 comprising a nanostructured first surface having nanofeatures and an opposite second surface; combining a second layer comprising the first major surface with the nanofeatured contacting 820 a portion, wherein the second layer is an organic layer; and reacting 830 at least one of the first material or the second material to secure the first and second layers together. The nanostructured first surface includes recessed features and / or protruding features formed from a single composition. Together, the nanofeatures of the first layer and the first major surface of the second layer define at least one void. In any embodiment, the first layer is brought into contact with the second layer by laminating the first and second layers together. Lamination of layers is well known and ...

Embodiment approach 1

[0104] Embodiment 1 is an article. The article includes a first layer including a nanostructured first surface having nanofeatures and an opposing second surface; and a second layer including a first host attached to a portion of the nanofeatures. surface. The nanostructured first surface includes recessed features or protruding features or both recessed and protruding features formed from a single composition. The second layer is the organic layer. Together, the nanofeatures of the first layer and the first major surface of the second layer define at least one void.

Abstract

The present disclosure provides an article comprising a layer having a nanostructured first surface comprising a nanofeature and an opposing second surface, and an organic layer comprising a major surface attached to a portion of the nanofeature. The nanostructured first surface includes protruding features and / or recessed features formed from a single composition. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article, the method comprising contacting the nanofeatures of the layer having the nanostructured surface with the major surface of the organic layer, and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device comprising the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

Description

technical field [0001] The present disclosure relates broadly to articles comprising nanostructured surfaces and methods of making such articles. Background technique [0002] Nanostructured surfaces can provide optical effects that can be used in a variety of applications such as improving the color and efficiency of devices (eg, OLED displays). A refractive index difference or contrast is required at the nanostructured interface of the nanostructured surface to provide the desired optical functionality. The nanostructured surface can be exposed to the surrounding environment to provide refractive index contrast; however, the exposed surface limits attachment of the nanostructured surface to other surfaces and is susceptible to damage and / or environmental contamination. Therefore, there remains a need for improvements in protecting nanostructured surfaces. Contents of the invention [0003] In a first aspect, an article is provided. The article includes a first layer i...
