Preparation and thermoelectric properties of flexible PEDOT:PSS coated Te nanorod/PEDOT nanowire composite films
Poly(3,4-ethylenedioxythiophene)nanowire(PEDOT NW)and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)coated Te nanorods(PC-Te)were successfully synthesized through a modified self-assembled micellar soft-template process and a wet chemical method,respectively.Flexible self-supporting PC-Te/PEDOT NW composite films were prepared via a vacuum filtration technology.The microstructures of the PC-Te were characterized by the transmission electron microscopy,and the influence of PC-Te content on thermoelectric performance of the composite film was investigated.As the increase of PC-Te content,the Seebeck coefficient of the samples increased,and the electrical conductivity were decreased.The composite film with 70%PC-Te achieved a maximum power factor of 47.4 μW/mK2(380 K).The composite film showed good flexibility,and after bending for 500 times,the resistance change rate was 9.2%.
