摘要

采用丝网印刷技术制备了聚(3,4-亚乙二氧基噻吩):聚(苯乙烯磺酸)(PEDOT:PSS)/双壁碳纳米管(DWCNT)薄膜，作为柔性热电发生器(TEG)的活性 p 型材料。通过改变油墨配方使其适合丝网印刷、改变碳纳米管浓度以及在乙二醇 (EG) 中处理印刷聚合物薄膜，PEDOT:PSS/碳纳米管复合材料的性能得到了优化。这项工作的目的是找到能优化完全印刷材料的电导率、塞贝克系数和功率因数的处理条件。从实验数据来看，用乙二醇化学处理的含有 10%（重量）DWCNT 的复合材料能最大限度地提高材料的导电率、塞贝克系数和功率因数。

Flexible Screen-Printed Thermoelectric Materials Based on PEDOT:PSS/DWCNT Composites

Screen printing technology is employed to prepare poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/double-walled carbon nanotubes (DWCNT) films as active p-type material for flexible thermoelectric generators (TEGs). Performance of the PEDOT:PSS/CNT composites have been optimized by changing the formulation inks to make them suitable for screen printing, by varying the CNT concentrations and by treating the printed polymeric films in ethylene glycol (EG). The purpose of this work is finding the processing conditions that optimize conductivity, Seebeck coefficient, and the power factor of the fully printed material. From experimental data, the composite with 10% by weight of DWCNT chemically treated in EG maximizes conductivity, Seebeck coefficient, and power factor of the material.
