Abstract:

An inexpensive polyimide-free alignment layer comprising a mixture of an epoxy and a reactive liquid crystal material is used for fabricating liquid crystal displays (LCDs). The alignment layer can be cast onto a previously aligned layer, without destroying the alignment of the underlying layer, thus allowing for monolithic fabrication of compensator stacks, without film transfer lamination.

C07F 7/18
C09D 183/04

US Classification:

427409, 4274192, 4274198

Abstract:

A method is provided for enhancing corrosion resistance of a metal surface that includes the step of forming a sol-gel coating in which nanostructured zinc phosphate (Zn(PO)) and zinc oxide (ZnO) phases are present in the mixture. The method may include the steps of mixing an organosilane, organometallic, organic acid, water, and alcohol, and allowing the components of the mixture to partially hydrolyze, followed by adding at least one component having zinc functionality and at least one component having phosphate functionality to the partially hydrolyzed mixture, wherein the zinc component and phosphate component are added in a molar ratio of from about 1. 5:1 to about 5:1 (Zn:PO). The resulting mixture can be applied as a coating to a metal surface to improve the corrosion resistance of the metal and to enhance the adhesion of resinous materials to the metal surface.

Appl. No.:

8/525429

Inventors:

Young Chung - Calabasas CA
Thomas A. Seder - Cedar Rapids IA

Assignee:

Rockwell International - Costa Mesa CA

International Classification:

H01J 6135

US Classification:

313485

Abstract:

An improved fluorescent lamp and a method of preparing the same are described. The fluorescent lamp includes a tube having a first surface which serves as a substrate. A continuous layer of aluminosilicate sol-gel material having phosphor particles embedded therein is formed on the first surface of the tube. The continuous layer of sol-gel material having phosphor particles embedded therein is formed by first preparing an aluminosilicate sol-gel solution. The phosphor particles are next mixed in the aluminosilicate sol-gel solution to obtain a phosphor particle carrying aluminosilicate sol-gel solution. Then, the first surface is coated with the phosphor particle carrying aluminosilicate sol-gel solution. The phosphor particle carrying aluminosilicate sol-gel solution is dried on the first surface to form a phosphor particle containing sol-gel layer.

Appl. No.:

8/524978

Inventors:

Young Chung - Calabasas CA

Assignee:

Rockwell International Corp. - Seal Beach CA

International Classification:

B05D 302

US Classification:

427380

Abstract:

An organically modified sol-gel method of preparing substantially crack-free aluminosilicates films is provided. Chelated aluminum alkoxide and polydimethylsiloxane are mixed in a 1:1 ratio by weight in a solvent and refluxed at approximately the boiling temperature of the solvent to produce a sol-gel liquid including polymerized aluminosilicates. The sol-gel liquid is cooled to room temperature. Additional solvent is added to the sol-gel liquid to reduce its viscosity. A substrate is coated with the reduced viscosity sol-gel liquid. The coating of sol-gel liquid on the substrate is dried to produce an organically modified aluminosilicates sol-gel film. The sol-gel film is heated, to enhance polymerization of the sol-gel film and to evaporate residual solvent, and then cooled.
