Highly improved thermoelectric performances of PEDOT:PSS/SWCNT composites by solvent treatment

PEDOT:PSS/SWCNT composites can be prepared by mixing aqueous dispersions of PEDOT:PSS and SWCNT at different weight ratios. By being soaked with DMSO for 2 min at room temperature, the PEDOT:PSS/SWCNT composite with an optimized SWCNT weight ratio of 74 wt% exhibits a promising power factor of 300 μW m−1 K−2, which is the highest among PEDOT:PSS and CNT composites.299
