The organic thermoelectric fibers with p- and n-type power factors of 378 ± 56 and 289 ± 98 μW m−1 K−2, respectively, were prepared via simple wet-spinning and post-treatment methods.

Free-standing single-walled carbon nanotube (SWCNT)/cellulose acetate composite films were fabricated by a simple bar-coating method. As a paste solvent, acetone, a low-boiling-point solvent, was used. By simple brushing of a polyethylenimine/ethanol solution, ntype thermoelectric composite films could be obtained. The optimal p-type and n-type power factors of the free-standing thermoelectric films were 1.41 ± 0.22 and 0.516 ± 0.172 μW cm −1 K −2 , respectively, at room temperature. We also fabricated the organic thermoelectric generator from the free-standing composite films and confirmed their electrical power generation capability. By applying the temperature difference of 10 K, the output power of 2.28 μW was obtained.
