Abstract

The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. 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 including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an 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 including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.
