dc.description.abstractThermoelectric (TE) generators that are capable of providing sustainable energy conversion under dynamic mechanical stresses have been explored for realizing autonomous wearable electronics. However, finding extremely deformable, efficient, and air-stable TE materials is still a major challenge. Here, we report highly stretchable and efficient organic TE materials from aqueous composites of poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) and ionic liquids (ILs). In this composite, ILs simultaneously enhance the Seebeck coefficient and electrical conductivity of PEDOT:PSS (up to 35 μV K -1 and 538 S cm -1 , respectively) by controlling its oxidation level and nanostructure. Moreover, the resulting fibrous structure with IL-assisted soft domains leads to outstanding mechanical deformability and durability, enabling that the PEDOT:PSS/IL films simply coated on elastomeric substrates maintain the TE functionality under tensile strain (ϵ) up to 70% and repetitive stretching cycles with 30% ϵ without severe degradation in TE performance. Furthermore, we also demonstrate the long-term TE stability of PEDOT:PSS/IL composites maintaining >80% of the initial performance after 10 days under ambient conditions. Our finding proves the potential of this novel composite as a stretchable and air-stable organic TE material.en_US
