Abstract

The invention discloses an antimony telluride / poly(3,4-ethylenedioxythiophene) / poly(styrene sulfonate) thermoelectric composite material and a manufacturing method of the antimony telluride / poly(3,4-ethylenedioxythiophene) / poly(styrene sulfonate) thermoelectric composite material, and belongs to the technical field of thermoelectric composite material synthesis. The manufacturing method comprises the steps that (1) antimony telluride nanopowder is prepared; (2) under the vacuum condition, spark plasma sintering is performed on the antimony telluride nanopowder prepared in the step (1), and then the antimony telluride nanopowder is cooled, so that an Sb2Te3 block material is obtained; (3) the Sb2Te3 block material prepared in the step (2) is cut, then is soaked in a poly(3,4-ethylenedioxythiophene) / poly(styrene sulfonate) solution and is stored at the temperature of 3 DEG C-5 DEG C for 20-40 days, so that the antimony telluride / poly(3,4-ethylenedioxythiophene) / poly(styrene sulfonate) thermoelectric composite material is obtained. The antimony telluride / poly(3,4-ethylenedioxythiophene) / poly(styrene sulfonate) thermoelectric composite material and the manufacturing method of the antimony telluride / poly(3,4-ethylenedioxythiophene) / poly(styrene sulfonate) thermoelectric composite material have the advantages that the process is low in energy consumption, the cost is low, and the process is simple; the composite material is good in thermoelectric performance and high in ZT value.

Description

technical field

[0001] The invention specifically relates to an antimony telluride / poly(3,4-ethylenedioxythiophene): polystyrene sulfonate thermoelectric composite material and a preparation method thereof, belonging to the field of thermoelectric composite material synthesis. Background technique

[0002] In today's society, the energy crisis is becoming more and more serious, and the research and development of new energy conversion materials is on the agenda. Thermoelectric material is a functional material that realizes mutual conversion of thermal energy and electrical energy through the movement of carriers inside a solid, and is mainly used in thermoelectric power generation and refrigeration. The performance of thermoelectric materials is evaluated by ZT (thermoelectric performance index): ZT=S 2 σT / K, where S is the Seebeck coefficient, σ is the electrical conductivity, T is the absolute temperature, and K is the thermal conductivity. An ideal thermoelectric mater...
