Preparation and Thermoelectric Properties of Composites Based on Polythiophene Derivatives with Donor-acceptor Structure |

| Abstract: | Poly{( 3-methylthiophene-2 , 5-diyl ) p-( nitro ) benzylidene ] ( 3-methylthiophenylene quinodime-thane-2,5-diyl)}(PMTNBQ) with low bandgap was synthesized and its thermoelectric properties were investi-gated. PMTNBQ/graphite( G) composites were prepared by mixing in solution followed by mechanical ball milling and cold pressing. The thermoelectric properties of the composites were investigated as a function of the graphite to polymer ratios. The highest value of ZT(5. 36í10-3 ) was obtained for the PMTNBQ/G composite containing 90% ( mass fraction ) of G. This work suggests that the thermoelectric properties of polymer-inorganic composites can be improved by synthesizing polymers with low band gap. |
