Abstract
Nanostructured material exhibiting a random anisotropic nanostructured surface, and exhibiting an average reflection at 60 degrees off angle less than 1 percent. The nanostructured materials are useful, for example, for optical and optoelectronic devices, displays, solar, light sensors, eye wear, camera lens, and glazing.

A method of making a nanostructured layer comprising a polymeric matrix and a nanoscale dispersed phase, the layer having a random anisotropic nanostructured surface, the random anisotropic nanostructured surface having an average reflection at 60 degrees off angle less than 1 percent, the layer having a thickness of at least 500 nm, and the layer having a visible light transmission through the thickness of the layer at 90 degrees to the random anisotropic nanostructured surface of at least 94 percent, the method comprising:
- providing the polymeric matrix comprising the nanodispersed phase;
- and
- anisotropically etching the polymeric matrix using plasma to form the random nanostructured surface.
