Publication number: 20110143045Abstract: Certain example embodiments of this invention relate to the use of graphene as a transparent conductive coating (TCC). A substrate having a surface to be coated is provided. A self-assembled monolayer (SAM) template is disposed on the surface to be coated. A precursor comprising a precursor molecule is provided, with the precursor molecule being a polycyclic aromatic hydrocarbon (PAH) and discotic molecule. The precursor is dissolved to form a solution. The solution is applied to the substrate having the SAM template disposed thereon. The precursor molecule is photochemically attached to the SAM template. The substrate is heated to at least 450 degrees C. to form a graphene-inclusive film. Advantageously, the graphene-inclusive film may be provided directly on the substrate, e.g., without the need for a liftoff process.Type: ApplicationFiled: December 15, 2009Publication date: June 16, 2011Inventor: Vijayen S.

Publication number: 20110117331Abstract: A method for manufacturing an optical film (1) is disclosed. The method comprises the step of providing a continuous sheet of transparent plastic material (2). One side of said sheet of transparent plastic material (2) is coated with a layer of curable transparent resin. The coating of curable transparent resin coating is embossed using an embossing roller (5) having a surface, with a predetermined surface structure, so as to provide a desired optical structure in said curable transparent resin. The curable transparent resin is cured, while the curable transparent resin is in contact with said embossing roller (5), so as to harden said desired optical structure.Type: ApplicationFiled: April 3, 2008Publication date: May 19, 2011Inventor: Henrik Bang Mikkelsen
