What is it about?
The PEDOT:PSS/SWCNT composite films with excellent thermoelectric properties could be fabricated by just mixing their water dispersion and washing the film to remove the surfactant.

Why is it important?
The fabrication method is quite simple; (1) just mixing the commercially available water dispersion of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) and single-wall carbon nanotube (SWCNT); (2) removal of surfactant, which was originally contained in SWCNT dispersion, by just dipping the film for only 2 minutes. The ZT value of the composite film was around 0.1.
Perspectives
Using the simple method (mixing and washing), we could obtain the PEDOT:PSS/SWCNT composite films with excellent thermoelectric properties. This method is useful from the viewpoint of industrial application.
