Bi2Te3 Organic-inorganic hybrid thermoelectric material comprising bismuth telluride and polymer of bulk type and the method for preparation thereof

摘要

The present invention provides an organic / inorganic hybrid thermoelectric material containing bulk Bi ₂ Te ₃ and a polymer. In the bulk organic-inorganic hybrid thermoelectric material according to the present invention, the polymer and Bi ₂ Te ₃ are physically and chemically bonded to change the electrical and thermal properties of the material, ultimately improving the thermoelectric performance index. In addition, it is a bulk type organic / inorganic hybrid thermoelectric material and exhibits properties suitable for the field of thermoelectric power generation. In addition, the method for producing a bulk organic-inorganic hybrid thermoelectric material according to the present invention can produce a Bi ₂ Te ₃ powder through a gas phase reduction method, thereby lowering a sintering temperature for producing a final organic / inorganic hybrid thermoelectric material, .
