摘要： A dispersion-preventing patterned substrate suitable for a liquid crystal display device is described. The substrate is patterned with a resin which is a cure of a coating composition comprising a solution of: a) a cross-linkable polymeric surfactant having i) at least one pendant fluorocarbon moiety, and ii) a plurality of pendant ionic moieties which are capable of reacting with counterions to form a cross-linked polymer; and b) a polymeric crosslinking agent having a plurality of ionic or potentially ionic moiety counterions capable of reacting with the ionic moieties of the surfactant, wherein the pattern defines a plurality of wells adapted to receive a coloring agent.

摘要： A hard drive disk substrate is formed of a multi-phase ceramic-based material having at least two phases with amorphous phases being present in an amount less than 1 volume percent based on the volume of the ceramic-based material or at least one phase being free metal. A process for producing the ceramic-based disk substrate is produced by forming a flat disk of a porous ceramic and then infiltrating the porous ceramic with a metal whereby a multi-phase ceramic-based computer hard drive disk is produced. Additionally, a step of passivating the porous ceramic by elevating it to a temperature of 1300 °C to 1800 °C before the infiltrating step may be performed, such that the surfaces are passivated and the reaction kinetics can be controlled during the infiltrating step. A preferred composite material is made of a multi-phase boron-carbide composite material including grains having peaks with an average roughness value, Ra, of between 1 to 200 Å, the roughness value being formed in situ by causing a microhardness gradient of between 19 and 3200 Kg/mm2 in the various phases of the multi-phase boron-carbide composite material.

摘要： The invention is a complex-shaped article, comprising an article prepared by joining at least one multi-phase ceramic-metal part and at least one shaped part of another material, wherein the theoretical density of the at least one ceramic-metal part is greater than 80 percent. In another aspect, the invention is a process for preparing complex-shaped articles, comprising: (a) forming at least one ceramic-metal part; (b) forming at least one shaped part of another material; and (c) joining the at least one shaped ceramic-metal part with the at least one shaped part of another material such that a complex-shaped article is formed. The invention is a less costly and time-consuming process for preparing complex-shaped composite articles wherein the articles are formed of two or more selected materials wherein one of the materials is a ceramic-metal composite.

摘要： The present invention is a laminate which comprises: a) a plastic substrate having a surface; b) an adhesion promoter layer which is a first plasma polymerized organosilicon compound deposited on the surface of the substrate in the substantial absence of oxygen; and c) a protective coating layer which is a second plasma polymerized organosilicon compound deposited on the surface of the adhesion layer at a power density from 106 J/kg to 108 J/kg, and in the presence of a sufficient stoichiometric excess of oxygen to form a silicon polymer of SiO¿1.8-2.4?C0.3-1.0 and H0.7-4.0. The coating layer provides abrasion and solvent resistance for the substrate, and the adhesion promoter prevents the coating layer from peeling off the substrate. The coated plastic substrate can be used in liquid crystal display devices as an alternative to glass.
