THERMOELECTRIC NANOMATERIALS Russian patent published in 2010 - IPC D01D5/00 

FIELD: chemistry.

SUBSTANCE: melt or solution is prepared first, where said melt or solution contains at least one substrate material or corresponding precursor compounds of substrate material and at least one thermoelectrically active material or a precursor compound of thermoelectrically active material. Further, the melt or solution undergoes electroformation. Fibre which contains at least one substrate material and at least one thermoelectrically active material and a precursor compound of thermoelectrically active material is obtained. If necessary, the precursor compound of the thermoelectrically active material is converted to active form. The thermoelectrically active material contains at least one compound which contains at least one element selected from a group consisting of tellurium and boron, or the thermoelectrically active material is selected from a group consisting of antimonides, silicides, germanides, skutterudites, clathrates, bismuth, NaCo₂O₄, Bi_2-xPb_xSr₂Co₂O_y, where x=0-0.6 and y=8+σ, rod-like monocrystals based on Cu-Co-O or Bi-Sr-Co-O, mixtures of oxides of formula SrTiO_mS_n (I), where 0≤n≤0.2 and 2≤m≤2.99, Ca₂Co₂O₅, NaCo₂O₄, Ca₂Co₄O₉ and their mixtures. Disclosed also is a method of producing nanotubes, nanowire and nanotubes, as well as use of nanowire and nanotubes in thermoelectric temperature control, for generating current, in sensors and for controlling temperature.

EFFECT: production of nanowire and nanotubes of sufficient length and constant quality, which enables high-precision temperature control.
