The method for preparation of nanocomposite with enhanced thermoelectric ability and nanocomposite thereof

摘要

The present invention relates to a method for producing a nanocomposite is produced and thus the thermal efficiency of the improved nanocomposite More particularly, has a coordination ligand, MO surface-treated (M = Cd or Zn) after the addition of a surfactant in preparing a MTe by injecting high-temperature Te metal powder (Step 1); In MTe prepared in step 1 N (N = Pb or Sn) by injecting the precursor core-step for producing a MTe-NTe of the cell structure (Step 2); And nanoparticles prepared in step 2 MTe-NTe and bulk mixing NTe by pre-heating, and then heat treatment step (step 3) The method for producing nanoparticles and MTe (M rectangle of the thermal efficiency is improved nanocomposite comprising a = Cd or Zn) round the NTe (N = Pb or Sn) is surrounded by a spherical shape of the core - would MTe-NTe NTe nanoparticles and bulk of the cell structure of the mixed nanocomposite. Improved method of producing the nanocomposite thermoelectric efficiency according to the present invention is a core having a uniform size using a high-temperature injection-cells may be produced nano-particles, by size, mixed with the bulk of PbTe or SnTe preparing a nanocomposite, thermal and electrical control characteristics at the same time because the improved thermal efficiency appears, thermoelectric cooling, and can be useful as a thermoelectric material for thermoelectric power generation applications.
