OS5-2-5 Developments of Flexible Organic Thermoelectric Materials

Abstract

Conducting polymers, such as polyaniline (PANI), polypyrrole, and polythiophene, have several attractive features for use as thermoelectric materials because of the thermal conductivity much lower than that of inorganic thermoelectric materials as well as their potential low cost due to available resources, easy synthesis, and easy processing into a versatile form. We report the thermoelectric properties of the (±)-10-camphorsulfonic acid (CSA) doped PANI films and poly (3,4-ethylenedioxythiophene)(PEDOT)-polystyrene sulphonic acid (PSS) films. We also evaluate the important properties, flexibility, durability, and thermal stability, for practical use of these conductive polymer films as thermoelectric materials.
