摘要：
In order to improve the thermoelectric performance of flexible wearable energy supply equipment, NaOH and dimethylsulfoxide (DMSO) are used together to dope poly (3, 4-ethylenedioxythiophene) -poly(styrenesulfonate) (PEDOT:PSS) to prepare NaOH/DMSO/PEDOT:PSS thermoelectric film, and the influence of NaOH and DMSO concentration on the conductivity, Seebeck coefficient and power factor of PEDOT:PSS were studied. Cotton/polyester spacer fabric was used as the substrate, and the photothermal-thermoelectric composite thermoelectric material was prepared by compounding NaOH/DMSO/PEDOT:PSS and coating ZrC/polyurethane (PU) photothermal layer, and the morphology, structure and thermoelectric properties of the composites were characterized. The results show that when 0. 5% NaOH and 3.5% DMSO are added, the power factor of NaOH/DMSO/PEDOT: PSS thermoelectric film reaches the peak value of 25.6 μW/(m•K2), which is 2 327 times that of pure PEDOT: PSS film. The Seebeck coefficient of the photothermal-thermoelectric composite material is 35.5 μV/K, and the voltage generated by the thermoelectric composite material under illumination after adding the photothermal layer is 6.3 times that of the thermoelectric composite material without a photothermal layer. © 2022 China Textile Engineering Society.
