Abstract: Disclosed is a thermoelectric composite material includes a thermoelectric material including crystal grains; and a MXene inserted at boundaries of the crystal grains consisting of the thermoelectric material. Accordingly, the thermoelectric composite material may have a reduced thermal conductivity and an increased electrical conductivity. Furthermore, mechanical properties of the thermoelectric composite material may be improved. Thus, the thermoelectric composite material may improve the thermoelectric ability of a thermoelectric module including the same. A method of manufacturing the thermoelectric composite material includes coating MXene on a surface of a thermoelectric material powder including crystal grains; and sintering the thermoelectric material powder coated with the MXene to form a sintered body including the MXene inserted at boundaries of the crystal grains consisting of the thermoelectric material.
