摘要
为得到一种新型的柔性可穿戴温差发电织物,通过聚(3,4-乙烯二氧噻吩)与聚苯乙烯磺酸(PEDOT/PSS)将碳纳米管(CNTs)均匀分散,采用浸渍-烘干法,制备CNTs/PEDOT/PSS温差发电复合材料。借助扫描电子显微镜、X射线衍射仪表征了该温差发电复合纺织材料的表面形貌和结晶情况,测试了不同质量分数CNTs下的Seebeck系数、电导率和热导率,通过计算热电优值讨论了其热电性能,并研究了透湿性、折皱回复性等服用性能。结果表明:随着CNTs质量分数的增加,Seebeck系数和电导率增大,热导率保持在较低的水平,热电优值增加,热电性能逐渐增强,透湿性稍有下降,折皱回复性得到提高;在CNTs质量分数为0.4%时,热电优值达到2.99×10^(-9)。
In order to obtain a novel flexible and wearable thermoelectric materials,(poly(3,4-ethylenedioxythiophene)and poly(4-styrenesulfonate)(PEDOT/PSS)were used to evenly disperse carbon nanotubes(CNTs)onto fabrics,CNTs/PEDOT/PSS thermoelectric composite textile materials were prepared by dipping-drying method.The surface morphology and crystallization of the thermoelectric composite textile materials were characterized by field\|emission scanning electron microscope and X ray diffraction.The Seebeck coefficient,electrical conductivity and thermal conductivity of CNTs composites with different contents were measured.The thermoelectric properties were studied by calculating the thermoelectrc figure of merit(ZT)value,and the wearability such as moisture permeability and wrinkle recovery were studied.The results show that with the increase of CNTs content,the Seebeck coefficient and the electrical conductivity are increased,and the thermal conductivity remains at a lower level,the ZT value is increased,the thermoelectric properties are gradually enhanced,the moisture permeability is decreased,but the wrinkle recovery is better.When the CNTs content is 0.4%,the ZT value reaches 2.99×10^-9.
