Abstract

Described herein are various methods for making textured articles, textured articles that have improved fingerprint resistance, and methods of using the textured articles. The methods generally make use of masks comprising nanostructured metal-containing features to produce textured surfaces that also comprise nanostructured features. These nanostructured features in the textured surfaces can render the surfaces hydrophobic and oleophobic, thereby beneficially providing the articles with improved fingerprint resistance relative to similar or identical articles that lack the texturing.
