THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT, ARTICLE FOR THERMOELECTRIC POWER GENERATION, AND POWER SOURCE FOR SENSOR

摘要

Provided are the following: a thermoelectric conversion element including, on a substrate, a first electrode, a thermoelectric conversion layer and a second electrode, in which the thermoelectric conversion layer contains an electroconductive nanomaterial having an average length in the major axis direction of at least 5 nm and a polymer compound having a repeating unit represented by the following Formula (1); an article for thermoelectric power generation and a power source for sensors, which use this thermoelectric conversion element; and a thermoelectric conversion material for forming the thermoelectric conversion layer, the thermoelectric conversion material containing the electroconductive nanomaterial described above and a polymer compound having a repeating unit represented by the following Formula (1).; ;In Formula (1), ring A represents a conjugated hydrocarbon ring or a conjugated heterocyclic ring; X represents a group having one or two or more atoms selected from the group consisting of a carbon atom, an oxygen atom, a sulfur atom, a nitrogen atom, a phosphorus atom, and a silicon atom, shared as ring-constituting atoms of the ring A; the average inter-unit distance of the ring A is 1.42 Å or less; R¹¹ and R¹² each independently represent a substituent, and may be bonded to each other to form a ring; and the symbol * represents a bonding position for the repeating unit.
