Van Xuan Hong Nguyen 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: 20040168613
    Abstract: The present invention provides a composition and method to form a release layer to reduce adhesion between a polymerizable layer and a substrate surface that selectively comes into contact with the polymerizable layer. The composition consists of di-functional perfluoro silane containing molecules, and mono-functional perfluoro silane containing molecules. The method features disposing a coating upon the surface from a composition having a perfluoro silane containing molecule that includes a mixture of the di-functional and mono-functional perfluoro silane containing molecules. The perfluoro silane containing molecules are connected to bonding regions of the surface to form a layer having contact regions. A sub-set of the mono-functional perfluoro silane containing molecules are attached to bonding regions positioned between bonding regions to which the di-functional perfluoro silane containing molecules are attached.

  • Publication number: 20040170770
    Abstract: The present invention provides a method to reduce adhesion between a polymerizable layer and a substrate surface that selectively comes into contact with the polymerizable layer. The method features disposing a coating upon the surface from a composition having a perfluoro silane containing molecule. The perfluoro silane molecule is connected to bonding regions on the surface forming covalent bonding groups, as well as contact regions. The contact regions include fluorinated chains of molecules. The covalent bonding groups are positioned between the surface and the contact regions. The perfluoro silane containing molecule may be applied to the surface as a monomolecular layer from a di-functional perfluoro silane molecule. Exemplary molecules that may be employed as the perfluoro silane containing molecule includes molecules sold under the trade-names FLUOROSYL™ FSD 2500 and FLUOROSYL™ FSD 4500.
