Exceptional thermoelectric properties of flexible organic-inorganic hybrids with monodispersed and periodic nanophase.

ABSTRACT: Flexible organic-inorganic hybrids are promising thermoelectric materials to recycle waste heat in versatile formats. However, current organic/inorganic hybrids suffer from inferior thermoelectric properties due to aggregate nanostructures. Here we demonstrate flexible organic-inorganic hybrids where size-tunable Bi₂Te₃ nanoparticles are discontinuously monodispersed in the continuous conductive polymer phase, completely distinct from traditional bi-continuous hybrids. Periodic nanofillers significantly scatter phonons while continuous conducting polymer phase provides favored electronic transport, resulting in ultrahigh power factor of ~1350 μW m^-1 K^-2 and ultralow in-plane thermal conductivity of ~0.7 W m^-1 K^-1.
