The effects of polyaniline (PANI) with different polymerization times on the film-forming and thermoelectric properties as well as on the performance of SWCNTs/PANI composites were systematically investigated in this study. It was found that the film-forming and flexibility of PANI films improved with the increase in polymerization time. We showed that a super high conductivity of ∼4000 S cm⁻¹ can be achieved for the SWCNTs/PANI composite film, which is the highest value for the SWCNTs/PANI system at present. Both the electrical conductivity and power factor increase by an order of magnitude than that of pure PANI films and far exceed the theoretical value of the mixture model. These results suggest that the sufficiently continuous and ordered regions on the interlayer between the filler and matrix are key to improve the electrical conductivity of composites. Finally, the maximum PF reaches 100 μW m⁻¹ K⁻² at 410 K for the 0.6CNT/PANI5h. Furthermore, it is found that the composite films have excellent environmental and structural stability. Our results can deepen the understanding of organic–inorganic thermoelectric composite systems and facilitate the practical application of flexible and wearable thermoelectric materials.

本研究系统地研究了不同聚合时间的聚苯胺（PANI）对单壁碳纳米管/聚苯胺复合材料的成膜和热电性能以及性能的影响。发现聚苯胺薄膜的成膜性和柔韧性随着聚合时间的增加而提高。^{我们展示了~4000 S cm -1}的超高电导率单壁碳纳米管/聚苯胺复合膜可以实现，是目前单壁碳纳米管/聚苯胺体系的最高值。电导率和功率因数均比纯聚苯胺薄膜增加一个数量级，远超过混合模型的理论值。这些结果表明，填料和基体之间的夹层上足够连续和有序的区域是提高复合材料导电性的关键。最后，最大PF达到100 μW m ^-1 K ^-20.6CNT/PANI5h 在 410 K。此外，发现复合膜具有优异的环境和结构稳定性。我们的研究结果可以加深对有机-无机热电复合体系的理解，促进柔性可穿戴热电材料的实际应用。
