摘要：
Composites of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) and single-wall carbon nanotube (SWCNT) were 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% exhibited a high electric conductivity of 3800 S cm(-1) and a reasonable Seebeck coefficient of 28 mu V K-1, leading to a promising power factor of 300 mu W m(-1) K-2 and a hopeful ZT value of 0.13. Possible reasons for the highly improved properties are carefully discussed. (C) 2017 Elsevier B.V. All rights reserved.
