Thermoelectric materials can be used as the active materials in thermoelectric generators and as Peltier coolers for direct energy conversion between heat and electricity. Apart from inorganic thermoelectric materials, thermoelectric polymers have been receiving great attention due to their unique advantages including low cost, high mechanical flexibility, light weight, low or no toxicity, and intrinsically low thermal conductivity. The power factor of thermoelectric polymers has been continuously rising, and the highest ZT value is more than 0.25 at room temperature. The power factor can be further improved by forming composites with nanomaterials. This article provides a review of recent developments on thermoelectric polymers and polymer composites. It focuses on the relationship between thermoelectric properties and the materials structure, including chemical structure, microstructure, dopants, and doping levels. Their thermoelectric properties can be further improved to be comparable to inorganic counterparts in the near future.

热电聚合物和复合材料的最新发展

热电材料可以用作热电发电机中的活性材料，也可以用作珀尔帖冷却器，用于在热和电之间直接进行能量转换。除无机热电材料外，热电聚合物还因其独特的优势而受到广泛关注，这些优势包括低成本，高机械柔韧性，重量轻，低毒性或无毒性以及固有的低热导率。热电聚合物的功率因数一直在不断提高，室温下的最高ZT值大于0.25。通过与纳米材料形成复合材料，可以进一步提高功率因数。本文概述了热电聚合物和聚合物复合材料的最新发展。它着重于热电性能和材料结构之间的关系，包括化学结构，微结构，掺杂剂和掺杂水平。在不久的将来，它们的热电性能可以进一步提高到与无机类似物相当的水平。
