In this study, we synthesized a flexible thermoelectric composite film consisting of poly(3,4-ethylenedioxythiopene)-poly(4-styrenesulfonate)-coated selenium nanowires (PEDOT:PSS-coated Se NWs) and multi-walled carbon nanotubes (MWCNTs) simple solution mixing. PEDOT:PSS-coated Se NWs were synthesized by coating PEDOT:PSS-on the surface of Se during the process of synthesizing Se NWs. Then, flexible PEDOT:PSS-coated Se/MWCNT composite films were synthesized by filtration. To verify the thermoelectric (TE) potential, the TE properties of the composite film with various MWCNT contents were investigated to determine the optimal conditions for improved TE performance. The maximum power factor of the composite film was ∼73.94 μW (m K), which is much higher than that of Se and PEDOT:PSS. This study suggests an approach to fabricate flexible inorganic/organic hybrid films with high TE performance.
在本研究中，我们通过简单的溶液混合合成了一种由聚（3,4-乙撑二氧噻吩）-聚（4-苯乙烯磺酸盐）包覆的硒纳米线（PEDOT:PSS包覆的Se NWs）和多壁碳纳米管（MWCNTs）组成的柔性热电复合薄膜。PEDOT:PSS包覆的Se NWs是在合成Se NWs的过程中通过在Se表面包覆PEDOT:PSS合成的。然后，通过过滤合成了柔性PEDOT:PSS包覆的Se/MWCNT复合薄膜。为了验证热电（TE）潜力，研究了具有不同MWCNT含量的复合薄膜的TE性能，以确定提高TE性能的最佳条件。复合薄膜的最大功率因数约为73.94 μW/（m·K²），远高于Se和PEDOT:PSS的功率因数。本研究提出了一种制备具有高TE性能的柔性无机/有机混合薄膜的方法。
