Conducting polymer-based hybrid materials with thermoelectric properties  
Main Page
The main drawback however, is the limited electric conductivity of the polymers. In the course of our research we prepare  organic/inorganic hybrids, in which we exploit the large Seebeck-coefficient of the polymer, and the high electric conductivity of  the incorporated nanoparticles (e.g., Au, Ag, nanoscopic carbon).   So far we prepared silver doped polythiophene derivatives and polypyrrole, with tunable conductivity and thermoelectric  property as well as bismuth telluride containing composites. New directions of our experiments are the study of conducting  polymers with 1D nanostructure (e.g., nanofibers), and to fill of carbon nanotube structure (arrays or carpets) with conducting  polymers.  References:  Study on the electrodeposition of organic and inorganic thermoelectric materials for composite preparation Krivan E, Bencsik G, Janaky C, et al.,   REACTION KINETICS AND CATALYSIS LETTERS   Volume: 96   Issue: 2   Pages: 429-436     Characterization of Poly(3-octylthiophene)/Silver nanocomposites prepared by solution doping   Pinter E, Fekete ZA, Berkesi O, et al.,   JOURNAL OF PHYSICAL CHEMISTRY C   Volume: 111   Issue: 32   Pages: 11872-11878    
Conducting polymers have prominently large Seebeck-coefficient - some cases it can  even exceed 1mV/K, which is five times larger than that of bismuth telluride (Bi2Te3), the most  frequently used inorganic thermoelectric material. This fact makes CPs attractive candidates for  fabricating new generation lightweight and flexible thermoelectric materials. In addition,  polymers generally have low thermal conductivity, which is also an important factor in the high  thermoelectric figure of merit.
