Abstract
We report the design and the thermoelectric properties of organic/inorganic composites made of Poly-pyrrole (PPy) and of two silicides (Co0.85Fe0.15Si and CrSi2). For both composites, we find a significant enhancement of the thermoelectric properties of the PPy with increasing content of the inorganic filler. The maximum power factor of the composites were up to 0.8 µW/m.K 2 for ϕi = 50% and of 2 µW/m.K 2 for ϕi = 90% for Co0.85Fe0.15Si and up to 3.37 µW/m.K 2 for ϕi = 50% and of 9.7 µW/m.K 2 for ϕi = 90% for CrSi2, more than two orders of magnitude higher than in pure PPy. This study proposed a novel and effective way to improve the thermoelectric performances of the thermoelectric polymer PPy.
