Abstract:
Provided are a thermoelectric material having a core-shell nanofiber structure and a method for preparing the same. The thermoelectric material having a core-shell nanofiber structure comprises: a thermoelectric semiconductor nanofiber core unit; and a heterogeneous thermoelectric semiconductor shell unit coated on the surface of the thermoelectric semiconductor nanofiber core unit. According to the present invention, the thermoelectric material having the core-shell nanofiber structure with high electrical conductivity and low thermal conductivity can be manufactured in large quantities in a short period of time.
Abstract:
The present invention relates to a method for manufacturing thermoelectric materials with a core-shell nanofiber structure. According to the present invention, the thermoelectric material with high electrical conductivity and low thermal conductivity is mass-produced for a short time by an electrospinning method. The method for manufacturing the thermoelectric materials with the core-shell nanofiber structure includes the steps of: preparing a first melt; preparing a second melt; obtaining a polymer-thermoelectric semiconductor precursor complex nanofiber; obtaining a thermoelectric semiconductor oxide nanofiber; and reducing the thermoelectric semiconductor oxide nanofiber.
