Abstract Several flexible thermoelectric composite fabrics, including poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/PEDOT/cotton, PEDOT:PSS/PEDOT/silk, and PEDOT:PSS/PEDOT/wool have been prepared by a gas polymerization combining solution coating process, and their thermoelectric properties have been measured from 300 to 360 K. The results show that both electrical conductivity and Seebeck coefficient of PEDOT/cotton, PEDOT/silk, and PEDOT/wool composite fabrics are significantly improved after the PEDOT:PSS coating treatment, leading to significant enhancement of power factors of the composite fabrics. In addition, both electrical conductivity and Seebeck coefficient of all the composite fabrics are insensitive to the temperature increasing from 300 to 360 K. A highest power factor of 0.5 μWm−1 K-2 has been achieved for the PEDOT:PSS/PEDOT/wool composite at 360 K. This work provides an effective method to endow fabrics with thermoelectric properties.

气体聚合结合溶液涂覆工艺制备的柔性复合织物的热电性能

摘要 制备了聚(3,4-乙撑二氧噻吩):聚(苯乙烯磺酸)(PEDOT:PSS)/PEDOT/棉、PEDOT:PSS/PEDOT/丝绸、PEDOT:PSS/PEDOT/羊毛等多种柔性热电复合织物。采用气体聚合结合溶液涂层工艺，在300~360 K范围内测得其热电性能。 结果表明，PEDOT/棉、PEDOT/丝、PEDOT/羊毛复合织物的电导率和塞贝克系数均有显着提高PEDOT:PSS涂层处理后，复合织物的功率因数显着提高。此外，所有复合织物的电导率和塞贝克系数对温度从 300 K 升高到 360 K 不敏感。最高功率因数为 0。
