  • Thermoelectric conversion material-containing resin composition and film formed from thermoelectric conversion material-containing resin composition
    Patent number: 10084124
    Abstract: Provided are a resin composition that enables simple formation of a film having excellent thermoelectric conversion characteristics and flexibility, and a film that is formed using the resin composition and that has excellent thermoelectric conversion characteristics and flexibility. A thermoelectric conversion material-containing resin composition contains (A) an insulating resin, (B) an inorganic thermoelectric conversion material, and (C) a charge transport material. A film is formed according to a commonly known method using the thermoelectric conversion material-containing resin composition. It is preferable that (B) the inorganic thermoelectric conversion material is in the form of fine tubes or fine wires. Single-walled carbon nanotubes are particularly preferable as (B) the inorganic thermoelectric conversion material.
