ABSTRACT
Thermoelectric materials can create a potential difference between two ends if there is a temperature diffrence between them. The present thermoelectric materials are made from the scarce elements in the earth such as bismuth, telluride or toxic metals like lead[Hanus et. al, 2017]. At the same they are high cost and rigid. Because of disadvantages of the these commercial thermoelectric materials, it was attempted to make polymeric thermoelectric materials with high performance [Shi et. al, 2017]. The
most promising polymer is poly(ethylene dioxythiophene) (PEDOT) and its nano composites [Kim et. al, 2017].
In this study, at first copper sulfide nanoparticles was synthesized by a simple solution method and
characterized by XRD, XPS and SEM. Then, PEDOT synthesized in the aqueous solution with poly
(styrene sulfonic acid). The composites of the polymer and copper sulfide nanoparticules were
prepared at various compositions by mixing them at ambient conditions. The electrical conductivity
and Seebeck coefficients of these nanocomposites were measured on films coated on a glass substrate.
