Abstract

Wearable devices based on organic thermoelectric (TE) fibers or textiles are attracting widespread attention because of their impressive structural features and high heat-to-electricity conversion capability. However, the production of low-cost, high-TE, and high-mechanical-performance TE fibers is still a challenge. Herein, a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) spinning solution were synthesized by low-temperature in situ polymerization and freeze–thaw (FT) treatment. Also PEDOT:PSS TE fibers were prepared by wet spinning. PEDOT:PSS fibers with excellent properties were obviously improved by regulating the polymerization reaction temperature and number of FT cycles. The optimized PEDOT:PSS fibers obtained at a pretty low in situ polymerization temperature (−18 °C) and FT2 cycles excited a considerably high Seebeck coefficient of 40.8 μV·K –1, a high electrical conductivity of 980 S·cm –1, and a tensile breaking strength of 57.42 cN. The method is cost-effective and could be realized in mass production, demonstrating its potential application in wearable electronic devices.
