Abstract
Official abstract text for this publication.
Provided herein are a thermoelectric material and a method for preparing the same, wherein the thermoelectric material has excellent thermoelectric performance and high mechanical properties (in particular, fracture toughness), and thus, when the thermoelectric material is applied to a thermoelectric module, the thermoelectric module has excellent performance and efficiency and a long lifespan.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing a thermoelectric material, the method comprising: (a) mixing first element powder and second element powder to obtain mixed powder, wherein the first element powder is selected from the group consisting of magnesium (Mg), bismuth (Bi), cobalt (Co), lead (Pb), silicon (Si), zinc (Zn), aluminum (Al), and manganese (Mn) and the second element powder is selected from the group consisting of silicon (Si), tellurium (Te), selenium (Se), stibium (Sb), and germanium (Ge); (b) mixing the mixed powder and a planar material to obtain a mixture, wherein the planar material is graphene; and (c) sintering the mixture, wherein, in step (c), the mixture is sintered at 600° C. to 900° C. for about 3 minutes to 1 hour under pressure of about 30 to 90 MPa. 2. The method according to claim 1 , wherein an organic solvent is added in step (b). 3. The method according to claim 2 , wherein the organic solvent is one or more selected from the group consisting of ethanol, acetone, and toluene. 4. The method according to claim 1 , wherein the planar material is a reduced graphene oxide. 5. The method according to claim 1 , wherein a thickness of the planar material is about 1 to 20 nm. 6. The method according to claim 1 , wherein an aspect ratio of the planar material is about 10 to 5,000. 7. The method according to claim 1 , wherein a content of the planar material is about 0.1 to 10 vol % with respect to 100 vol % of the thermoelectric material.
