摘　　要：为提高柔性可穿戴供能设备的热电性能,首先利用NaOH和二甲亚砜(DMSO)共同掺杂聚(3,4-乙烯二氧噻吩)-聚苯乙烯磺酸(PEDOT:PSS)制备NaOH/DMSO/PEDOT:PSS热电膜,研究了NaOH及DMSO质量分数对PEDOT:PSS电导率、塞贝克系数以及功率因数的影响;然后以棉/涤纶间隔织物为基材,通过复合NaOH/DMSO/PEDOT:PSS并涂覆ZrC/聚氨酯(PU)光热层制备光热-热电复合材料,并对复合材料的形貌结构和热电性能等进行表征。结果表明:当添加质量分数为0.5%的NaOH及3.5%的DMSO时,NaOH/DMSO/PEDOT:PSS热电膜的功率因数达到最高,为25.6μW/(m·K^(2)),是纯PEDOT:PSS膜的2327倍;光热-热电复合材料的塞贝克系数为35.5μV/K,添加ZrC/PU光热层后复合材料在光照下产生的电压为无光热层复合材料的6.3倍。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 25.6μW/(m·K^(2)),which is 2327 times that of pure PEDOT:PSS film.The Seebeck coefficient of the photothermal-thermoelectric composite material is 35.5μV/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.
