Description

technical field

[0001] The invention relates to a method for synthesizing and thin film preparation of a polymer thermoelectric material with high conductivity and high Seebeck coefficient and its application, and belongs to the technical field of polymer thermoelectric materials. Background technique

[0002] Thermoelectric conversion materials can realize mutual conversion between thermal energy and electric energy through the Seebeck effect and Peltier effect, and are expected to directly convert a large amount of industrial waste heat, solar heat, etc. into green electric energy. It is a new type of clean energy technology, and high The development of high-performance thermoelectric conversion materials has been the focus of research in this field.

[0003] At present, high-performance thermoelectric materials are mainly based on inorganic materials (such as Bi 2 Te 3 ), this type of material has high thermal conductivity, expensive raw materials and harsh preparation ...
