Hybrid organic thermoelectric (HOTE) materials have been considered as a promising alternative for future energy harvesting. Herein, a HOTE thin film was proposed and fabricated by a simple method. Highly conductive poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) developed by vacuum filtration has significantly contributed to the optimization of single-walled carbon nanotubes (SWNTs)/PEDOT:PSS (SN–PP) thermoelectric composite films. PEDOT:PSS was coated on the surface of SWNTs, effectively creating electrical connecting junctions between SWNTs. The SN–PP composite films achieved high electrical conductivity and Seebeck coefficient as well as a relatively low thermal conductivity simultaneously. A notable ZT value of 0.12 was obtained at 60 wt% SWNTs, which is generally higher than those reported in previous studies. Our approach may provide quite a useful strategy to prepare HOTE materials with high performance.

高性能混合有机热电SWNTs / PEDOT：PSS薄膜，用于能量收集

混合有机热电（HOTE）材料已被认为是未来能量收集的有前途的替代方法。在此，提出并通过简单的方法制造了HOTE薄膜。通过真空过滤开发的高导电性聚（3,4-乙撑二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）极大地促进了单壁碳纳米管（SWNT）/ PEDOT：PSS（SN–PP）热电的优化复合膜。PEDOT：PSS涂在单壁碳纳米管的表面上，有效地在单壁碳纳米管之间建立了电连接结。SN-PP复合膜同时实现了高电导率和塞贝克系数以及相对较低的热导率。著名的ZT60％（重量）单壁碳纳米管时获得的值为0.12，通常高于先前研究中报道的值。我们的方法可能为制备高性能HOTE材料提供了非常有用的策略。
