Patent number: 9688863Abstract: Disclosed herein are polysilsesquioxane-based anti-reflective coating (ARC) compositions, methods of preparation, and methods of deposition on a substrate. In one embodiment, the polysilsesquioxane of this disclosure is prepared in a two-step process of acid catalyzed hydrolysis of organoalkoxysilane followed by addition of tetralkoxysilane that generates silicone polymers with >40 mol % silanol based on Si-NMR. These high silanol siloxane polymers are stable and have a long shelf-life in polar organic solvents at room temperature. Also disclosed are low refractive index ARC made from these compositions with and without additives such as porogens, templates, thermal radical initiator, photo radical initiators, crosslinkers, Si—OH condensation catalyst and nano-fillers. Also disclosed are methods and apparatus for applying coatings to flat substrates including substrate pre-treatment processes, coating processes and coating curing processes including skin-curing using hot-air knives.Type: GrantFiled: June 15, 2016Date of Patent: June 27, 2017Assignee: Enki Technology, Inc.Inventors: Sina Maghsoodi, Brenor L. Brophy, Thomas E. Colson, Peter R. Gonsalves, Ze'ev R. Abrams

Patent number: 9376593Abstract: Disclosed herein are coating materials and methods for applying a top-layer coating that is durable, abrasion resistant, highly transparent, hydrophobic, low-friction, moisture-sealing, anti-soiling, and self-cleaning to an existing conventional high temperature anti-reflective coating. The top coat imparts superior durability performance and new properties to the under-laying conventional high temperature anti-reflective coating without reducing the anti-reflectiveness of the coating. Methods and data for optimizing the relative thickness of the under-layer high temperature anti-reflective coating and the top-layer thickness for optimizing optical performance are also disclosed.Type: GrantFiled: September 17, 2015Date of Patent: June 28, 2016Assignee: Enki Technology, Inc.Inventors: Sina Maghsoodi, Brenor L. Brophy, Ze'ev R. Abrams, Peter R. Gonsalves

Patent number: 9376589Abstract: Disclosed herein are single layer transparent coatings with an anti-reflective property, a hydrophobic property, and that are highly abrasion resistant. The single layer transparent coatings contain a plurality of oblate voids. At least 1% of the oblate voids are open to a surface of the single layer transparent coatings.Type: GrantFiled: July 14, 2015Date of Patent: June 28, 2016Assignee: Enki Technology, Inc.Inventors: Sina Maghsoodi, Brenor L. Brophy, Thomas E. Colson, Peter R. Gonsalves, Ze'ev R. Abrams

Patent number: 9314811Abstract: Disclosed is a coating apparatus including flow coating and roll-coating that may be used for uniform sol-gel coating of substrates such as glass, solar panels, windows or part of an electronic display. Also disclosed are methods for substrate preparation, flow coating and roll coating. Lastly, systems and methods for curing sol-gel coatings deposited onto the surface of glass substrates using high temperature air-knives, infrared emitters and direct heat applicators are disclosed.Type: GrantFiled: May 11, 2015Date of Patent: April 19, 2016Assignee: Enki Technology, Inc.Inventors: Brenor L.

Publication number: 20120271293Abstract: This invention relates to the targeting of specific tissue for destruction or modification using electromagnetic radiation coupled with nanoparticles to locally apply heat to the targeted tissue by concentrating the energy in a temporary or permanently placed medium. In general, this invention addresses the need to ablate, i.e., to reduce, eliminate, or to impede growth in specific tissue; and, to do so in a highly targeted and completely controllable implementation. Specific examples are described, focusing on, but not limited to, the retardation, reduction, and/or elimination of obstructing material and tissue in vascular stents and gastro-esophageal valves. For illustrative purposes, other examples are mentioned. Ablation is induced by the nano-plasmonic effect in metallic-based nanoparticles including, but not limited to, gold and gold coated nanoparticles; a wide variety of alternate materials are equally suitable.Type: ApplicationFiled: September 15, 2011Publication date: October 25, 2012Inventors: Ze'ev R.
