| Popis: | INTRODUCTION Poly(3,4ethylenedioxythiophene):poly(styre nesulfonate) (PEDOT:PSS) is a widely investigated ionic conducting polymer (ICP) in many research aspects and serves also as a promising thermoelectric polymer along with its potentially high and tunable electrical conductivity. The effectiveness of a thermoelectric material is related to the dimensionless figure-of-merit (ZT) defined as rST/r, where r is the electrical conductivity, S is the Seebeck coefficient, j is the thermal conductivity, and T is the absolute temperature. Ongoing research efforts on PEDOT:PSS are largely targeted at improving the electrical conductivity mainly due to less-effective strategies in modifying Seebeck coefficient and the intrinsically low thermal conductivity. |
