Abstract:
A preparation method for a metal matrix composite wire includes the following steps: 1) preparing a metal inner core; 2) preparing a glass-resin mixture; 3) dissolving self-adhesive resin in the solvent to prepare a self-adhesive resin solution; 4) uniformly coating the glass-resin mixture on a surface of the metal inner core, then coating the self-adhesive resin solution on a surface of the glass-resin mixture, and performing drying at a temperature of 80° C. to 150° C.; and 5) repeating the step 4) until a thickness of the coating reaches 2 to 10 μm. When an inductor is prepared by using the composite wire, the inductor may have relatively good weather resistance, a relatively good dielectric voltage-withstand capability, as well as relatively good high-temperature resistance and electrical performance.

Abstract:
A method of making a plasma display panel, whereby an address electrode is formed on a front substrate, a green sheet is formed to cover the address electrode, a dielectric layer pattern is formed by exposing, developing, and firing the green sheet, a composition for a display electrode is filled in the dielectric layer pattern and then fired to form a patterned display electrode, and a dielectric layer is formed to cover the patterned display electrode, thereby fabricating a front substrate. The green sheet includes a first green sheet that is formed using a dielectric composition, and a second green sheet that is formed on the first green sheet and using a photosensitive dielectric composition.

Abstract:
A process for preparing a composition for producing nanostructured mouldings and layers comprises contacting an aqueous and/or alcoholic sol of a compound of an element selected from silicon sand metals of the main groups and transition groups of the Periodic Table with species possessing hydrolysable alkoxy groups and comprising at least one organically modified alkoxysilane or a precondensate derived therefrom, under conditions which lead to (further) hydrolysis of the species, and subsequent removal of the alcohol formed and any alcohol already present originally. The process is characterized in that the alcohol is removed in an amount such that the residual alcohol content of the composition is not more than 20% by weight.
Abstract:
Polymeric catalysts (e.g., polymeric acid catalysts such as poly(styrene)sulfonic acid) can be used in the synthesis of sol-gel derived ceramic materials from metal alkoxides, for example, organic/inorganic hybrid materials formed by reaction of a metal alkoxide and a reactive endcapped polymeric modifier. The use of a polymeric catalyst, rather than a conventional monomeric (inorganic or organic) acid catalyst, has a non-deleterious effect on the aging behavior and offers potential for control of rheological properties (spinnability, coatability, etc.) of the hybrid materials.
