Problems solved by technology

[0003] At present, conductive polymers still have the following problems as thermoelectric materials: (1) Poor stability
Usually conductive polymer thermoelectric materials have better conductivity after doping, but as the conductivity increases, the Seebeck coefficient decreases significantly, so the obtained energy factor is low, and it is difficult to obtain high performance. thermoelectric materials

Description

technical field [0001] The invention relates to the technical field of conductive polymer pyroelectric materials, in particular to a method for manufacturing a flexible conductive polymer pyroelectric nano film with high pyroelectric coefficient. Background technique [0002] With the approaching of the energy crisis, the research of conductive polymer thermoelectric materials has attracted more and more attention. Compared with inorganic thermoelectric materials, the thermoelectric properties of the reported conductive polymer thermoelectric materials are average, and the thermal stability is relatively poor, so the development of conductive polymer thermoelectric materials is relatively slow. However, due to the outstanding advantages of abundant resources, low price, easy synthesis, easy processing, and low thermal conductivity, conductive polymer materials are considered to be one of the most promising thermoelectric materials. In recent years, the thermoelectric prop...
