Document Type and Number:
WIPO Patent Application WO/2015/190743
Kind Code:

Abstract:
The present invention relates to a thermoelectric composite having a thermoelectric property and a method for preparing the same, the thermoelectric composite comprising: a thermoplastic polymer which forms a matrix; and one or more electrically conductive materials which are dispersed on a grainboundary between particles of the thermoplastic polymer, thereby forming an electrically conductive pathway, the electrically conductive materials being selected from among a chalcogen material and chalcogenide, the chalcogen material comprising at least one material selected from among sulfur (S), selenium (Se), tellurium (Te) and polonium (Po), and the chalcogenide being a compound comprising at least one chalcogen selected from among sulfur (S), selenium (Se), tellurium (Te) and polonium (Po), wherein the average size of the electrically conductive materials is less than the average size of the particles of the thermoplastic polymer, and thermal conductivity is in the range of 0.1-0.5 W/m·K. The electrically conductive pathway in which the electrically conductive materials having a thermoelectric property forms a direct contact is formed within the matrix of the thermoplastic polymer, and the electrically conductive materials are arranged on the grainboundary between the particles of the thermoplastic polymer at a desired position of the matrix of the thermoplastic polymer. Accordingly, the present invention is capable of producing an optimal thermoelectric property with a minimum electrically conductive material content, and of maximizing phonon-scattering that occurs during a thermal transfer without restricting the movement of electrons within the thermoplastic polymer matrix by the electrically conductive materials having a thermoelectric property.
