Abstract: An injection mold insert with hierarchical structures and a method for method of making such injection mold inserts are provided. The method includes imprinting a primary imprint structure on an article and imprinting a secondary imprint structure on the primary imprint structure on the article. The secondary imprint structure includes a plurality of shapes, each of the plurality of shapes being substantially smaller than shapes of the primary imprint structure. The method further includes bonding the article to a substrate, sputter-coating the article with a metal film as an electroforming seed layer, and electroforming the injection mold insert over the article. Finally, the method includes dissolving the article to define the injection mold insert having a negative replica of the primary and secondary imprint structures.

Abstract: The present invention provides a textured polymer substrate comprising nano-sized surface features that are arranged in a single array or in a hierarchical array, and at least one layer of an amorphous, hydrophilic layer deposited thereon. The disclosed textured polymer substrate is advantageously suited for providing anti-reflective, anti-fogging and anti-UV materials.
