Abstract
Thermoelectric(TE)materials enable effective and direct energy conversions between heat and elec-tricity,displaying wide applications including waste/low-grade heat harvesting,local cooling,sensing and wearable electronics.Among the recently-developed organic and composite TE materials,poly(3,4-ethylenedioxythiophene)(PEDOT)is perhaps the most successful and frequently reported type.Herein,we aim to review the recent advances of the synthesis,mechanism and applications of PEDOT-based TE composites.First,the research background and the history of TE materials are briefly introduced.Next,the synthesis and TE performance of PEDOT-based composites are summarized according to the sequence of films,hydrogels/aerogels and fibers/yarns.Then,the mechanism,structure and property are elucidated.After that,the recent development and its applications of power generation and sensing are highlighted.Finally,we provide an outlook on the prospects and the challenges of PEDOT-based TE com-posites.
