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

Abstract

The embodiment of the present invention discloses a method for manufacturing a conductive polymer pyroelectric nano film, which includes: preparing a conductive polymer nanowire film by a template method, then preparing a conductive polymer nanowire film by a LB film method, and finally using a chemical method to prepare a conductive polymer nanowire film. The nanowire film is doped and reduced to obtain a conductive polymer pyroelectric nano film structure.

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, research on 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 properties...
