Reduced thermal conductivity of PEDOT:PSS nanotubes for high thermoelectric efficiency |
| 초록 |
Low dimensional materials exhibit fascinating functionalities differently from those in their bulk form, due to the large surface to volume ratio. Recently, low dimensional conducting polymers (CPs) have been extensively investigated owing to their enhanced electrical conductivity ( ＞ 1000 S/cm) due to improving the charge transport ability. We successfully fabricated PEDOT:PSS nanotubes via infiltration in AAO template. The transmission electron microscopy (TEM) studies reveal the formation of PEDOT:PSS nanotubes with an average wall thickness of 60 nm. Raman spectra confirm the stretching in the PEDOT:PSS Cα= Cβ bond with a linear alignment. We found a decrease in the thermal conductivity through phonon scattering at the inner and outer interfaces of the nanotube. The low thermal conductivity of the PEDOT:PSS nanotubes will be beneficial to realize highly efficient organic thermoelectric devices. |
