Abstract
A polyacrylonitrile (PAN)-based nanocomposite with 20 wt.% Fe-Co/C has been prepared by infrared pyrolysis. Morphological and structural studies revealed that the composite consists of polyacrylonitrile as a plastifier, Fe-Co as a filler alloy, and carbon, which was formed during combustion of the polymer. Electrical resistivity and thermal conductivity of the composite are rather low at ambient temperatures and do not exceed 1 Ohm m and 0.5 W/m K, respectively. However, due to a very low Seebeck coefficient, the calculated figure of merit ZT of the nanocomposite does not exceed 2.1 × 10−8.
