Thermoelectric and mechanical performances of ionic liquid-modulated PEDOT:PSS/SWCNT composites at high temperatures

Significant progress has been achieved for flexible polymer thermoelectric (TE) composites in the last decade due to their potential application wearable devices and sensors. In sharp contrast exceptional increase TE studies at room temperature, mechanical performance of received relatively less attention despite significance high-temperature environments. The performances poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/single-walled carbon nanotube (PEDOT:PSS/SWCNT) composite films with an ionic liquid (IL) (referred as “PEDOT:PSS/SWCNT-IL”) high temperatures are studied present work. fabricated show increasing temperature SWCNT content. maximum value power factor reaches 301.35 μW m-1 K-2 470 K PEDOT:PSS/SWCNT-IL composite. Furthermore, addition IL improves elongation break compared IL-free composites. This work promotes advancement widens applications different ranges.
