摘要

为了利用柔性热电材料进行能量收集,复合材料在可穿戴电子设备中具有广阔的应用前景,并且需要采用能够产生高热电性能复合材料的加工方法。在此,我们报告了通过在碳纳米管薄膜(CNTF)上聚合聚吡咯(PPy)制备柔性碳纳米管薄膜(CNTF)/聚吡咯(PPy)复合材料的方法。CNTF 的二维网络结构可以解决 CNT/PPy 因 CNT 的分散性和取向性差而对热电性能造成的限制。CNTF/PPy 复合材料在 300 K 时的最大热电功率因数为 369.2 μWmK,几乎是 CNTF(191.2 μWmK)的两倍。复合材料在反复弯曲时也显示出柔韧性。这种方法为优化基于 CNTF 的复合材料的热电特性提供了一条途径。该研究对热电转换和多功能可穿戴电子产品领域的应用前景具有重要意义。

Enhanced thermoelectric properties of flexible self-supporting carbon nanotube film/polypyrrole composites

Enhanced thermoelectric properties of flexible self-supporting carbon nanotube film/polypyrrole composites
For energy harvesting by flexible thermoelectrics, composite materials have prospects for wearable electronics and require processing methods yielding composites with high thermoelectric performance. Here, we report the fabrication of flexible carbon nanotube film (CNTF)/polypyrrole (PPy) composites by polymerization of PPy on the CNTF. The two-dimensional network structure of CNTF can solve the limitations on the thermoelectric performance of CNT/PPy caused by the poor dispersion and orientation of CNTs. The CNTF/PPy composites exhibit a maximum thermoelectric power factor of 369.2 μWmK at 300 K, which is nearly twice of that of the CNTF (191.2 μWmK). The composites also display flexibility under repeated bending. Composites treated with pre-stretching obtain a higher power factor of 403.8 μWmK at 320 K. This method provides a pathway for optimizing the thermoelectric properties of composites based on CNTF. The study is of importance for application prospects in the fields of thermoelectric conversion and multifunctional wearable electronics.
