- Abstract
- Herein, polyaniline-coated silver selenide nanowire/polyvinylidene fluoride (PANI-Ag2Se/PVDF) composite are synthesized using simple approach and their application to flexible thermoelectric (TE) film are demonstrated. The TE power factor of PANI-Ag2Se filler was analyzed with various coating cycle of PANI, which was considered by carrier transport properties. For the composite film with 65 wt% of NWs an optimized power factor of ~ 196.6 μW/m K2 is obtained at 300 K. After bending for 1000 cycles, only ~ 8% of the initial power factor is decreased, exhibiting a flexibility. A 6-leg TE device assembled with the synthesized composite film, and this device generated ~ 15.4 mV and a maximum power of ~ 835.8 nW at a temperature difference (∆T) of ~ 30 K. Additionally, this flexible TE device displays a power density of ~ 2.33 W/m2 at same ∆T. This study can guide the manufacturing of high-performance flexible TE composite films consisting of inorganic/organic hybrid materials. © 2021 Elsevier B.V.
