This disclosure features use of a paper or polymer film that includes a slip agent that can transfer to its surfaces. Once the paper or film is pressed against a glass sheet, this will leave a thin surface roughness of slip agent that can prevent or reduce glass surface scratches from other surfaces or particles during shipping or finishing (e.g., cutting to size, conveyance of glass), thereby improving the yield of glass shipments between glass forming plants and customers. The thin discontinuous layer of slip agent remaining on the glass surface can be washed off easily in subsequent washing processes. The paper or film can have the slip agent imbibed within the paper or coated on it as a surface member.

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, SiOH 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. Also disclosed are coating compositions and formulations for highly tunable, durable, highly abrasion-resistant functionalized anti-reflective coatings.

A method produces a control element having a touch-enabled surface, in which a paste-like material is applied on a carrier plate. At least one raised structure element is formed by the paste-like material on the carrier plate. For this purpose, a stencil having inherent stiffness is arranged above the carrier plate and the paste-like material is pushed through at least one recess in the stencil.

Disclosed herein is a method of forming a glass coating including making a sol by hydrolyzing an organosilane in the presence of a least one solvent and at least one catalyst, further adding at least one alkoxysilane, and aging the sol for at least 24 hours.

The present invention relates to synthesizing reduced graphene oxide on the surface of a metal sheet and glass. The invention particularly relates to a process for coating a substrate with reduced graphene oxide using seedlac as a carbon source. As per the process of the current invention, a solution of seedlac is prepared in an alcohol and the substrate is dipped in to the solution for one or more time. The substrate is then dried in air for 1-10 minutes and thereafter, heated to a temperature range of 400 to 1200 C. under controlled atmosphere of Ar/N.sub.2/ArH.sub.2/N.sub.2H.sub.2 at a different flow rate ranging from 100 to 500 seem for a period of 10 to 120 minutes.

Described herein are methods for creating spill-proof or spill-resistant surfaces through the use of hydrophobic or oleophobic (H-SH) edges, borders and/or boundaries that contain the water and other liquids within the inside edges, borders and/or boundaries. Also described herein are spill-proof/spill-resistant surfaces. Liquid (e.g., water and other aqueous solutions/suspensions) heights of 3-6 mm on a level planar surface can be sustained by such edges, borders and/or boundaries. The H-SH borders can be created on glass, metal, wood, plastic, and concrete surfaces.

A composition of matter is described in which a porous material, such as polydimethylsiloxane (PDMS), is coated with parylene N, C, D, or AF-4 by vapor deposition polymerization while a temperature of the porous material's surface being coated is heated to between 60 C. and 120 C., or 80 C. and 85 C., during deposition. The parylene forms nano roots within the porous material that connect with a conformal surface coating of parylene. In some embodiments, a watertight separation chamber in an integrated microfluidic liquid chromatography device is fabricated by heating tunnels in micro-fabricated PDMS and depositing parylene within the heated tunnels.

An etching device includes a stage on which a target substrate is disposed, a nozzle part disposed to face the stage with the target substrate interposed therebetween, where the nozzle sprays an etching solution toward the stage, a mask part disposed between the target substrate and the nozzle part, where the mask part includes a first pattern including a first side surface extending in a first direction, and a second pattern spaced apart from the first pattern in a second direction intersecting the first direction and including a second side surface extending in the first direction, and an opening is defined by the first side surface and the second side surface to expose a portion of the target substrate, and a lower cooling part disposed between the stage and the target substrate.

A coated glass element includes: a glass surface; and a coating that coats at least part of the glass surface. The coating includes at least one layer.
