P型有机热电聚合物材料的研究进展

Progress of p-type conjugated thermoelectric materials

热电材料通过热电效应可以实现热能与电能之间的相互转化,在医疗、太空、军事和日常生活中发挥着越来越重要的作用。有机热电材料原料来源丰富,结构可进行针对性的设计剪裁,同时具备轻、薄、柔和大面积溶液制备的特点,在最近进入了快速发展的阶段,其热电性能取得了显著的提升。总结了从20世纪80年代开始到目前为止p型聚合物热电材料的演变和性能进展,分成了4个部分展开讨论,集中在聚合物的针对性结构设计,和聚合物与掺杂剂掺杂工程的优化。最后进行了总结并对未来的发展方向进行了展望。

Thermoelectric materials can realize the mutual conversion between thermal energy and electric energy through the thermoelectric effect,and play an increasingly important role in medical treatment,space,military and daily life.Organic thermoelectric materials have rich sources of raw materials,and their structures can be tailored in a targeted manner.At the same time,they have the characteristics of light,thin,soft,and large-area solution preparation.They have recently entered a stage of rapid development,and their thermoelectric properties have been significantly improved.This paper summarizes the evolution and performance progress of p-type polymer thermoelectric materials since the 1980s,and divides the discussion into four parts,focusing on the targeted structural design of polymers,and the incorporation of polymers with dopants.Finally,a summary and an outlook on the future development direction are given.
