http://www.freepatentsonline.com/7923075.html

Nanostructured surfaces can improve the display performance of LCDs and can provide protection coatings. This patent teaches a method to achieve nanostructured coatings at low cost. Claim 1 reads:

1. A method for creating a nanotextured surface, comprising

(a) depositing a polymer film on a substrate; and

(b) transforming the polymer film into uniform islands of a regularly shaped, nanometer sized template solely by a microwave-assisted hydro- or solvo-thermal treatment.
