We developed poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) and polyethylene oxide composites and demonstrated their use for soft and stretchable thin film thermoelectric devices. A stable thermoelectric performance can be observed under 20% stretching. Due to the vast processability of the polyethylene oxide polymer, bulk size thermoelectric devices can be produced with scalable manufacturing techniques, such as hot compression molding and 3D printing. These techniques allow for devices with a large area and customized geometry.

PEDOT：用于可拉伸和3D打印的热电设备的PSS-聚环氧乙烷复合材料

我们开发了聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）和聚环氧乙烷复合材料，并展示了它们在柔软和可拉伸的薄膜热电器件中的用途。在20％拉伸下可以观察到稳定的热电性能。由于聚环氧乙烷聚合物具有巨大的加工性能，因此可以采用可扩展的制造技术（例如热压成型和3D打印）来生产大尺寸的热电器件。这些技术使设备具有大面积和定制的几何形状。
