这一观点讨论了聚合物热电理论，确定了可能导致最高效率的电子载流子能量和导热机制的组合。综述了近年来一些聚合物基热电材料的结构、电导率、塞贝克系数和性能指标。给出了定义这些量的基本方程，这些方程也与导热系数有关。最后，根据理论模型提出了优化热电性能的聚合物复合材料设计方法。
This perspective discusses theories of polymer thermoelectrics, identifying combinations of electronic charge carrier energies and thermal conductivity mechanisms that could lead to the highest efficiencies. Structures, electrical conductivities, Seebeck coefficients, and figures of merit are summarized for some recently devised polymer-based thermoelectric materials. Foundational equations that define these quantities are presented, and are related to thermal conductivities as well. Finally, approaches to polymer composite design that optimize thermoelectric performance in light of the theoretical models are proposed.
