▎ 摘　　要

NOVELTY - A thermoelectric material (1) comprises thermoelectric composite structure containing a set of pores (2), and graphene (3) disposed between the set of pores and doped with a non-metallic element. USE - A thermoelectric material for thermoelectric device and thermoelectric module (all claimed). ADVANTAGE - The thermoelectric materials have excellent thermoelectric properties. Because gaps between 1st pattern layer and 2nd pattern layer are directly adhered together by using the adhering process without using indirectly adhering by deposition using a metal, contact resistance may be reduced in the thermoelectric module including the thermoelectric material. In addition, the thermoelectric material may be mass produced within a short time. The thermoelectric module including the prepared thermoelectric material may have high current density and thermoelectric efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) thermoelectric material (1) comprising a self-standing flexible thermoelectric composite structure containing polymer layer having glass transition temperature (Tg) of greater than or equal to 50 degrees C and thin film of a material having a Seebeck coefficient of plus minus 1 mu V/K or greater coated on one surface of the polymer layer; (2) preparation of thermoelectric material which involves mixing polymer template solution containing non-metallic element and graphene solution, dispersing mixture to prepare a dispersion, and preparing thermoelectric composite structure by filtering and drying the dispersion and heat-treating the dried resultant under a reducing atmosphere; (3) preparation of thermoelectric material which involves coating thin film of material having a Seebeck coefficient of plus minus 1 mu V/K or greater on one surface of a substrate, coating polymer precursor solution for forming polymer having a Tg of greater than or equal to 50 degrees C on a top surface of the material thin film, forming polymer layer on the top surface of the material thin film by curing the polymer precursor solution, and preparing self-standing flexible thermoelectric composite structure by separating the polymer layer formed on the top surface of the material thin film from the substrate; and (4) preparation of thermoelectric material which involves disposing 1st mask layer having 1st pattern on a substrate, forming 1st pattern layer on the substrate by spraying 1st dispersion on the 1st mask layer, removing 1st mask layer from substrate and disposing 2nd mask layer having 2nd pattern opposite to 1st pattern layer on the substrate on which 1st pattern layer is formed, forming 2nd pattern layer having 2nd pattern on substrate by spraying 2nd dispersion on 2nd mask layer, and preparing thermoelectric material by removing 2nd mask layer from substrate and adhering 1st pattern layer and 2nd pattern layer formed on the substrate together.
