柔性热电发电机（FTEG）是新兴的能量收集设备，由于其可扩展性和低成本而引起了最近的研究兴趣。 FTEG 的制造需要在柔性基板上印刷热电元件。聚合物的低导热性、溶液加工性和低成本使其成为柔性设备的有吸引力的选择。采用它们的一个主要挑战是它们的导电率非常低。共轭聚合物的电导率可以通过掺杂和添加活性颗粒来提高。本文介绍了使用 2,3,5,6-四氟-7,7,8,8-四氰基醌二甲烷 (F4TCNQ) 作为掺杂剂来增强聚 (3-己基噻吩) (P3HT) 聚合物的热电性能。对于聚合物中 17 wt% 的掺杂剂，获得的最高电导率为 1.6 S/cm。对于相同的掺杂浓度，还获得了最高的塞贝克系数（102 μV/K）和功率因数（1.6 μW/mK2）。由于使用了o...
Flexible thermoelectric generators (FTEGs) are emerging energy harvesting devices that have generated recent research interest because of their scalability and low cost. The fabrication of FTEGs requires printing of thermoelectric elements on flexible substrates. The low thermal conductivity, solution processability, and low cost of polymers make them an attractive choice for flexible devices. A major challenge in their adoption is their very low electrical conductivity. The electrical conductivity of conjugated polymers can be improved by doping and addition of active particles. This article describes enhancements in the thermoelectric properties of poly(3-hexylthiophene) (P3HT) polymer using 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) as a dopant. The highest electrical conductivity obtained was 1.6 S/cm for 17 wt % dopant in the polymer. The highest Seebeck coefficient (102 μV/K) and power factor (1.6 μW/mK2) were also obtained for the same dopant concentration. As a result of using o...
