Light-weight, mechanically flexible, transparent thermoelectric devices are promising as portable, and easy-to-integrate energy sources. Poly(3,4-ethylenedioxythiophene) nanowires (PEDOT NWs) possessing high electrical conductivity were synthesized by a facile self-assembled micellar soft-template method. And then, Te nanowires (Te NWs) with high Seebeck coefficient were easily synthesized by the solution process and then added as an inorganic filler to form the PEDOT NW/Te NW nanocomposite films a simple and convenient vacuum filtration method. The thermoelectric (TE) properties of the nanocomposites were characterized in this research. A maximum power factor of 58.03 μW m K is obtained from the film containing 90 wt% Te NWs at room temperature, which is dozens of times that of the pure PEDOT NW film. This work uses the as-prepared PEDOT NWs/Te NW (90 wt%) nanocomposite film to fabricate a flexible thermoelectric generator and an output voltage of 2.8 mV was generated at a temperature difference of 13.5 K between the environment and human body.
轻质、机械柔性、透明的热电器件有望成为便携式且易于集成的能源。通过简便的自组装胶束软模板法合成了具有高电导率的聚（3,4-乙撑二氧噻吩）纳米线（PEDOT NWs）。然后，通过溶液法轻松合成了具有高塞贝克系数的碲纳米线（Te NWs），并通过简单便捷的真空过滤法将其作为无机填料添加以形成PEDOT NW/Te NW纳米复合薄膜。本研究对纳米复合材料的热电（TE）性能进行了表征。在室温下，含90 wt% Te NWs的薄膜获得了58.03 μW m K的最大功率因子，这是纯PEDOT NW薄膜的数十倍。这项工作使用制备好的PEDOT NWs/Te NW（90 wt%）纳米复合薄膜制造了一个柔性热电器，在环境与人体之间13.5 K的温差下产生了2.8 mV的输出电压。
