Polyaniline (PANI)-based thermoelectric (TE) materials have attracted considerable attention for flexible electronic energy harvesting devices because of properties such as solution processibility, excellent environmental stability, and low cost. However, the typical opposite dependence between electrical conductivity and Seebeck coefficient impedes their development, and tremendous efforts have been devoted to increasing their TE efficiency. This mini review focuses on key strategies in developing high-performance PANI-based TE materials, including doping engineering (fine-tuning of doping level), modulation of molecular orientation, inorganic nanoparticles incorporation to combine the merits of their components, interface engineering that introduces interfacial interactions and an energy-filtering effect, and other strategies. With properly optimized components, microstructure, and fabrication processing, which aid in the carrier transport properties, the overall performance of PANI-based TE composites has been greatly enhanced, promoting the improvement of PANI-based composites for sustainable energy utilization.

聚苯胺基热电复合材料的最新进展
聚苯胺 (PANI) 基热电 (TE) 材料由于具有溶液加工性、优异的环境稳定性和低成本等特性,在柔性电子能量收集设备中引起了广泛关注。然而,电导率和塞贝克系数之间典型的相反依赖性阻碍了它们的发展,并且已经付出了巨大的努力来提高它们的 TE 效率。这篇简短的评论侧重于开发基于 PANI 的高性能 TE 材料的关键策略,包括掺杂工程(掺杂水平的微调)、分子取向的调制、无机纳米粒子的结合以结合其组分的优点、引入界面工程界面相互作用和能量过滤效应,以及其他策略。
