在这项研究中，我们报告了使用层状Bi 2Se 3纳米板/聚偏氟乙烯（PVDF）复合材料作为热电材料的n型柔性热电织物的制造。这些复合材料的室温Seebeck系数和电导率值分别为-80 μ V·K ~（-1）和5100 S·m ~（-1），导致功率因数接近30 μ W·m ~（-1）·K ~（-2）。温度依赖性的热电性能表明，该复合材料具有金属般的导电性，而热电功率的特征在于由一个异质模型。这些复合材料有可能用于热电的非典型应用，其中轻质和柔性材料将是有益的。实际上，弯曲测试显示热电织物具有优异的耐久性。我们预计，这项工作可能会指导的方式来制造高性能的热电织物的基础上分层V-VI纳米片。
In this study, we report the fabrication of n-type flexible thermoelectric fabrics using layered Bi2Se3 nanoplate/polyvinylidene fluoride (PVDF) composites as the thermoelectric material. These composites exhibit room temperature Seebeck coefficient and electrical conductivity values of -80 mu V K-1 and 5100 S m(-1), respectively, resulting in a power factor approaching 30 mu W m(-1)K(-2). The temperature-dependent thermoelectric properties reveal that the composites exhibit metallic-like electrical conductivity, whereas the thermoelectric power is characterized by a heterogeneous model. These composites have the potential to be used in atypical applications for thermoelectrics, where lightweight and flexible materials would be beneficial. Indeed, bending tests revealed excellent durability of the thermoelectric fabrics. We anticipate that this work may guide the way for fabricating high performance thermoelectric fabrics based on layered V-VI nanoplates.
