Abstract:
The present invention relates to a method for manufacturing a thermoelectric nanocomposite and, more specifically, to a method for manufacturing a thermoelectric nanocomposite which comprises the steps of: preparing a solution in which a bulk material is dispersed in a polymer matrix; and generating a nanostructure from the bulk material dispersed solution. According to the present invention, the thermoelectric nanocomposite having high thermoelectric effect and electrical conductivity can be formed by a simple process.
Abstract:
PURPOSE: A surface treating method of ceramic particles is provided to improve the solvent wettability and dispersibility of ceramic particles by treating the surfaces of the ceramic particles with an ionic polymer. CONSTITUTION: The surface property of ceramic particles, of which surfaces are treated with an ionic polymer, is possibly controlled. The ionic polymer is an anionic polymer and is one of poly (acrylic acid), poly (sodium 4-styrene sulfonate), poly (vinyl sulfonic acid), poly (sodium salt), and poly (amino acid). The ionic polymer is a cationic polymer and is one of poly (diallydimethylammonium chloride), poly (allylamine hydrochloride), poly (4-vinyl benzyl trimethyl ammonium chloride), and poly (ethylene imine). A surface treating method of ceramic particles includes the steps of: adjusting the pH of a solution containing ceramic particles using a predetermined solution; and controlling the surface property of the ceramic particles using an ionic polymer.

Abstract:
PURPOSE: A via paste is provided to minimize the contraction by being hardened at the temperature lower then a sintering process, and to prepare a non-sintering ceramic hybrid substrate with excellent conductivity even when a polymer binder is present. CONSTITUTION: A via paste for a non-sintering ceramic hybrid substrate comprises conductive powder, thermosetting resin, thermal hardener and solvent. The conductive powder comprises fine conductive powder 40~90 weight% and ultrafine conductive powder 10~60 weight% with an average particle diameter of 0.3~10 micron smaller than the ultrafine conductive powder.
