| Abstract: | 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. |
