The poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)-based thermoelectrics are a potential candidate for wearable power generator, owing to their low thermal conductivity(κ), flexibility, light weight, etc. However, the thermoelectric efficiency of PEDOT:PSS is still low due to the low electrical conductivity (σ)and the low Seebeck coefficient (S). Here we propose the fabrication of 1-dimensional nanotube structure of PEDOT:PSS to study the thermoelectric transport in low dimensional PEDOT:PSS. The 1D-PEDOT:PSS structure possesses an improved hole mobility resulting from stretched chains in linear growth of nanotube as well as low κ resulting from phonon scattering at interfaces, which increases the thermoelectric efficiency of PEDOT:PSS. We believe that the PEDOT:PSS nanotubes not only enhances the thermoelectric efficiency but also opens a new era toward the thermoelectric applications using low dimensional polymers. |
