1. A method for manufacturing a thermoelectric polymer film, comprising:
mixing a conductive polymer liquid and a plurality of carbon nanotubes to form a mixture;
coating the mixture on a substrate to form a film precursor by spin coating;
arranging two electrode parts on a top surface of the film precursor;
applying an alternating current electric field to the film precursor through the two electrode parts at a room temperature, wherein applying the alternating current electric field to the film precursor through the two electrode parts at the room temperature is to connect the two electrode parts with a power source, a voltage of the power source is 5 V to 30 V, and a power-on time is greater than or equal to 0.5 hour and less than or equal to 2.5 hours, so as to change an arrangement of the plurality of carbon nanotubes, such that the plurality of carbon nanotubes form an oriented arrangement; and
drying the film precursor at the room temperature to form the thermoelectric polymer film.
