  • Patent number: 8634146
    Abstract: A method of making a nanostructure is provided that includes applying a thin, random discontinuous masking layer (105) to a major surface (103) of a substrate (101) by plasma chemical vapor deposition. The substrate (101) can be a polymer, an inorganic material, an alloy, or a solid solution. The masking layer (105) can include the reaction product of plasma chemical vapor deposition using a reactant gas comprising a compound selected from the group consisting of organosilicon compounds, metal alkyls, metal isopropoxides, metal acetylacetonates, and metal halides. Portions (107) of the substrate (101) not protected by the masking layer (105) are then etched away by reactive ion etching to make the nanostructures.

  • Publication number: 20130299214
    Abstract: The present disclosure provides an article having (a) a substrate having a first nanostructured surface that is antireflective when exposed to air and an opposing second surface; and (b) a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces defining a plurality of open area cells. The micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. The traces of the conductor micropattern have a specular reflectance in a direction orthogonal to and toward the first surface of the substrate of less than 50%. Each of the traces has a width from 0.5 to 10 micrometer. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers.
