摘要

通过改进的自组装胶束软模板法和湿化学法分别成功合成了聚(3,4-乙烯二氧噻吩)纳米线(PEDOT NW)和聚(3,4-乙烯二氧噻吩):聚苯乙烯磺酸(PEDOT:PSS)修饰的Te纳米棒(PC-Te),采用真空抽滤工艺制备了柔性自支撑PC-Te/PEDOT NW复合薄膜.通过透射电子显微镜等对PC-Te的显微结构进行表征,研究了PC-Te的添加量对复合薄膜的热电性能的影响规律.随着PC-Te含量的增加,复合薄膜的Seebeck系数增大,电导率减小,PC-Te含量为 70%时,复合薄膜的功率因子的最大值达到 47.4 μW/mK2(380 K).该薄膜具有良好的柔性,弯曲 500次后,其电阻变化率为9.2%.

Abstract

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%.
