Outline of Final Research Achievements |
In this study, we reported general methods for studying the thermoelectric properties of a polymer film in both the in-plane and through-plane directions. The bench-mark PEDOT:PSS films have highly anisotropic carrier transport properties and thermal conductivity. The anisotropic carrier transport properties and thermal conductivity can be explained by the lamellar structure of the PEDOT:PSS films where the PEDOT nanocrystals could be isolated by the insulating PSS in the through-plane direction. This study highlights the parameters for figure-of-merit calculation in organic thermoelectric materials must be obtained on the same direction.
