Abstract: This application relates to an anti-stiction flexible mold comprising a layer of an anti-stiction silicon dioxide deposited onto a flexible substrate. There is also provided a method for fabricating an anti-stiction flexible mold comprising the steps of a) depositing a layer of silicon dioxide on a flexible substrate; and b) interacting the layer of silicon dioxide with an anti-stiction agent to form the anti-stiction flexible mold. The resulting anti-stiction flexible mold may have superior anti-stick properties and may enable easy separation of mold and substrates after imprinting.

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.

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: This invention relates to a UV-curable coating material comprising an organosilica compound such as POSS or octahedral oligomeric silsesquioxane which is functionalized with a UV-curable functional group. The material further comprises at least one UV-curable cross-linker. The coating material comprises surface structures in the nano-sized range and can be used in a nanoimprint coating process where the material is coated on a substrate such as glass and a mold is pressed against the material to form an imprint before curing by UV radiation.
