Abstract Recently, organic polymer-based thermoelectric (TE) hybrids or composites have received significant attention. Here, a unique layered morphology of polypyrrole/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/single-walled carbon nanotube (PPy/PEDOT:PSS/SWCNT) ternary TE composites are designed using 1D nanostruture of PPy as template. The nanowires of PPy/PEDOT:PSS binary composites are obtained via coating PEDOT:PSS on the surfaces of 1D PPy nanowires. Interestingly, the PPy/PEDOT:PSS/SWCNT ternary composites reveal unexpected layered morphology and dramatically-enhanced TE function with an optimal power factor of 45.3 ± 1.4 μW m−1 K−2 at room temperature. This study will enrich the structure design and preparation strategy of novel TE composites by judicious combing 1D polymer nanostructure with 3D layered networks of composites.

以一维聚合物纳米结构为模板制备的具有独特层状结构的聚吡咯/PEDOT:PSS/碳纳米管三元热电复合材料

摘要 近年来，基于有机聚合物的热电 (TE) 杂化材料或复合材料受到了广泛关注。在这里，使用 PPy 的一维纳米结构作为模板设计了聚吡咯/聚（3,4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）/单壁碳纳米管（PPy/PEDOT：PSS/SWCNT）三元热电复合材料的独特层状形态. PPy/PEDOT:PSS二元复合材料的纳米线是通过在一维PPy纳米线表面涂覆PEDOT:PSS获得的。有趣的是，PPy/PEDOT:PSS/SWCNT 三元复合材料显示出意想不到的层状形态和显着增强的 TE 功能，室温下的最佳功率因数为 45.3 ± 1.4 μW m-1 K-2。
