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 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. The anisotropic thermal conductivity
was mainly attributed to the lattice contribution from PSS because
the polymer chain is oriented along the substrate.
