Abstract Inspired by worm morphology, this study report a low-cost and facile synthesis approach to construct a worm-like P-type flexible thermoelectric material—poly(3,4-ethylene dioxythiophene):p-toluenesulfonic acid (PEDOT:Tos) coated polypropylene (PP) nonwoven fabrics via low-temperature interfacial polymerization. This as-prepared thermoelectric fabric made of fibers with a core-shell structure has an electrical conductivity of 2.19 S/cm and the Seebeck coefficient of 16.15 μV K−1 at a temperature difference of 30 °C. Furthermore, it presents good mechanical and washing stability by bending and ultrasonic test. A thermoelectric device designed of five pairs of thermoelectric material (p-type) and copper wire (n-type) generates 0.512 mV voltage at a temperature difference of 10 °C. This thermoelectric device has a prospect in the application of portable and interactive devices. This study proposes an easy way to manufacture bioinspired thermoelectric fabric with high thermoelectric performance and high potential applications, such as in wearable and flexible sensors.

蠕虫状PEDOT：通过低温界面聚合的Tos涂层聚丙烯织物用于高效热电纺织品

摘要 受蠕虫形态的启发，本研究报告了一种低成本、简便的合成方法来构建蠕虫状 P 型柔性热电材料——聚（3,4-乙烯二氧噻吩）：对甲苯磺酸（PEDOT：Tos）涂层通过低温界面聚合制备聚丙烯（PP）无纺布。这种由具有核壳结构的纤维制成的热电织物在 30°C 的温差下具有 2.19 S/cm 的电导率和 16.15 μV K-1 的塞贝克系数。此外，它通过弯曲和超声波测试表现出良好的机械和洗涤稳定性。由五对热电材料（p 型）和铜线（n 型）设计的热电器件在 10 °C 的温差下产生 0.512 mV 电压。这种热电器件在便携式和交互设备的应用中具有前景。这项研究提出了一种简单的方法来制造具有高热电性能和高潜力应用的仿生热电织物，例如可穿戴和柔性传感器。
