Thermoelectric materials are known for their ability to convert heat energy in to electrical energy. This can be achieved due to their characteristic low thermal conductivity and high electrical conductivity. Usually these materials are various inorganic compounds consisting of Bi, Te and other metallic elements. However, in recent years polymer based thermoelectric composites have received attention because of many benefits that they can provide to thermoelectric materials like lower density, cost reduction and mechanical flexibility [1]. In this work thermoelectric Sb2Te3 and Bi2Se3 fillers were synthesized on multi-walled carbon nanotube (MWCNT) surface by physical vapor deposition method [2]. Then obtained hybrid fillers were mixed into aqueous polyvinyl alcohol (PVA) dispersion to obtain PVA/MWCNT-Sb2Te3 and PVA/MWCNT-Bi2Se3 thermoelectric polymer composites. Flexible free-standing films of thermoelectric polymer composites for the characterization were obtained by solution casting.
