“…Nevertheless, a breakthrough was achieved by controlling the doping and oxidation level of poly(3,4-ethylenedioxythiophene) (PEDOT). For example, PEDOT composites generate zT = 0.42 at room temperature, which is comparable to those of some traditional inorganic materials [6,[16][17][18][19][20]. Organic/inorganic hybridization is another promising way to improve the thermoelectric performance of polymers [21][22][23].…”

A significant enhancement in the thermoelectric performance was observed for three-dimensional conducting aerogels, which were obtained from poly(3,4-ethylenedioxythiophene) : poly(4-styrenesulfonic) (PEDOT:PSS) and multiwalled carbon nanotubes (MWCNTs) suspensions by adding different concentrations of metallic silver (Ag). It was found that the electrical conductivity and Seebeck coefficient could be simultaneously increased with the unique structure. Moreover, the conducting aerogels have an ultralow thermal conductivity (0.06 W m −1 K −1 ) and a large Brunauer-Emmett-Teller surface area (228 m 2 g −1 ). The highest figure of merit (zT) value in this study was 7.56×10 −3 at room temperature upon the addition of 33.32 wt.% Ag. Although the zT value was too low, our work may provide new insights into the design and development of the thermoelectric material for applications. Further investigation with PEDOT:PSS aerogels will be continued to get an economical, lightweight, and efficient polymer thermoelectric material.

Three different in situ chemical oxidative polymerization routes, that is, (A) spin-coating and subsequent liquid layer polymerization, (B) spin-coating followed by vapor phase polymerization, and (C) in situ polymerization and then post-treatment by immersion in ethylene glycol (EG), have been developed to achieve poly(3,4-ethylenedioxythiophene)/reduced graphene oxide (PEDOT/rGO) nanocomposites. As demonstrated by scanning electron microscopic and energy-dispersive X-ray spectroscopic techniques, PEDOT has been successfully coated on the surface of the rGO nanosheets by each of the three preparation routes. Importantly, all of the nanocomposites display a greatly enhanced thermoelectric performance (power factors) relative to those of the corresponding neat PEDOT.
