Recently thermoelectric materials have been studied extensively as emerging green energy harvesting technique because they can convert waste heat into electricity via the Seebeck effect. Among the various types of thermoelectric materials, in this study, we have investigated thermoelectric behavior of polybenzimidazole (PBI)-based hybrid nanocomposite films with containing 1-20 wt% multiwalled carbon nanotube (MWCNT), which were fabricated via a facile solution-casting method. For the purpose, the morphological features, electrical properties and thermal stability of the hybrid nanocomposite films were characterized by using an electron microscope, ohmmeter, and thermogravimetric analyzer, respectively. In order to identify the thermoelectric behavior of the PBI/MWCNT nanocomposite films, the Seebeck coefficients and power factors were also evaluated with a digital multimeter and two temperature controllable Peltier elements. |
