聚(3,4-乙撑二氧噻吩)-聚(苯乙烯磺酸盐)共聚物(PEDOT:PSS)的热输运由电子导热分量和声子导热分量共同贡献。这些导电聚合物的电导率和热导率之间的关系在热电能量转换中具有极大的兴趣。在这项工作中,我们表征了单根PEDOT:PSS纳米纤维的轴向电导率和热导率,并发现在300 K下的Lorenz数L大于Sommerfeld值L0。此外,我们发现,L在低温区显著增加。我们认为,这种趋势是由于低水平的导电聚合物的双极性贡献和电子的贡献,在低温区的热导率的增加趋势。
The thermal transport of Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) nanofiber is contributed by the electronic component of thermal conduction and the phonon component of thermal conduction. The relationship between the electrical conductivity and thermal conductivity of these conducting polymers is of great interest in thermoelectric energy conversation. In this work, we characterized the axial electrical conductivities and thermal conductivities of the single PEDOT:PSS nanofibers and found that the Lorenz number L is larger than Sommerfeld value L0 at 300 K. In addition, we found that the L increased significantly in the low-temperature region. We consider that this trend is due to the bipolar contribution of conducting polymers with low-level electrical conductivity and the increasing trend of the electronic contribution to thermal conductivity in low-temperature regions.
