Abstract:
A silicate material, comprising a silicate domain and one or more substantially nonsilicate domains. The material is produced by mixing a templating mixture with a precured resin and one or more resin precursors. The templating mixture is preferably comprised of one or more surfactants, one or more alcohols and water. A precured resin is formed by reacting one or more silicate resin precursors with water, and preferably in the presence of a co-solvent and a catalyst. The precured resin is mixed with the templating mixture and preferably with an additional amount of one or more silicate precursors. The invention also includes a method for fabricating the silicate material, a holographic medium, an optical article, and a method for fabricating an optical article.
Abstract:
A glass composite material comprising a polymer chain selected from the group consisting of polysilane, polygermane, polystannane and a copolymer thereof, and a network structure of a metal oxide consisting of a metal atom bonded to the other metal atom through an oxygen atom, wherein the polymer chain is chemically crosslinked with a glass matrix of the network structure of the metal oxide directly or indirectly, and a volume resistivity measured by setting a ratio of a voltage to a film thickness at 10.sup.6 V/cm according to a disc plate electrode method is not more than 3.times.10.sup.6 .OMEGA.cm.
Abstract:
This invention relates to sol-gel methods for forming non-shrinking, high-glass composite materials and the products. Also taught is an inorganic-organic composite material having a solid interwoven network of an inorganic polymer matrix with interpenetrating polymerized alcohols. The inorganic matrix can be based on either Si or Ti atoms.
Abstract:
This invention is directed to an alloy, and a method of producing an alloy, of increased resistance to moisture, comprising a melt mixture of at least one phosphate glass, at least one organic thermoplastic or thermosetting polymer, and an amount of a water soluble stabilizer component which provides a source of metal cations having a valency of 2.sup.+ or higher The amount of the stabilizer component added is that amount effective to improve the alloy's resistance to moisture. Preferably, the alloy is comprised of: (a) 5-80% of the matrix material; (b) 15-90% of the phosphate glass; and, (c) 0.1 to 40% of the stabilizer component. Additionally, the metal cations which are found in the stabilizer component and which form part of the insoluble surface layer are preferably selected from the group consisting of Ba.sup.2+, Mg.sup.2+, Ca.sup.2+, Al.sup.3+, Zn.sup.2+, Sr.sup.+2 and Fe.sup.3+.

Abstract:
This invention is directed to the preparation of alloy articles consisting essentially of glass and/or glass-ceramic and an organic thermoplastic or thermosetting polymer having a working temperature compatible with that of the glass and/or the precursor glass for the glass-ceramic. The glass and polymer are combined at the working temperature to form an intimate mixture; i.e., the glass and polymer are in a sufficiently fluid state to be blended together to yield a body exhibiting an essentially uniform, fine-grained microstructure wherein, desirably, there is at least partial miscibility and/or a reaction between the glass and the polymer to promote adhesion and bonding therebetween. A body is shaped from the mixture and cooled to room temperature.
