Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) functionalized Te (PF-Te) nano rods were in situ synthesized. A simple and efficient vacuum-assisted filtration method was employed to integrate the PF-Te nanorods with PEDOT:PSS to form PEDOT:PSS/PF-Te composite films. By varying the content of PF-Te nanorods, the Seebeck coefficient of the composites increases from 15.6 to 51.6 mu V/K, while the electrical conductivity decreases from 1262 to 122.4 S/cm. A maximum power factor of 51.4 mu W/mK(2) is obtained from a sample containing 70 wt% PF-Te nanorods at room temperature. An 8 single-leg flexible thermoelectric generator prototype was fabricated using the as-prepared PEDOT:PSS/PF-Te composite film containing 70 wt% PF-Te on a polyimide substrate with Ag electrodes. The prototype produced an output voltage of 2.5 mV at a 13.4 K temperature difference between human body and the environment. (C) 2017 Published by Elsevier Ltd.
