Mohamed Sultan Mohiddin SAIFULLAH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200331172
    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.

  • Patent number: 10494295
    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.

  • Publication number: 20180311877
    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.

  • Publication number: 20180059291
    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.
