Investigation into thermoelectric performance of a flexible n-type nanocomposite film from the AgxSe nanotube composited with PPy
Source abstract
Abstract
Silver selenide (Ag 2Se) has turn up as a promising n-type thermoelectric (TE) material. Especially, the Ag 2 Se nanotubes may be more attractive in view of their one-dimensional hollow tubular nanostructure. Regrettably, the TE application of Ag 2 Se nanotubes has not yet been reported so far, probably due to their hard accessibility and poor processability. In this work, we developed a simple and efficient template-free electrochemical deposition method for preparing Ag xSe nanotubes, and thus investigated the TE application of the Ag x Se-nanotube films electrochemically composited with polypyrrole (PPy). It was found that the incorporation of PPy into the n-type Ag x Se-nanotube films not only settled the issues of their high brittleness and easy oxidation, but also significantly improved their TE performance through the synergistic effects. Consequently, the Ag x Se nanotube/PPy composite film achieved a maximum power factor of 282.8 ± 16.5 μW m −1 K −2, which is nearly twice that of the pure Ag xSe-nanotube film.
