摘要：

This study investigates a coating method for doping a single-walled carbon nanotube (SWCNT)/poly(3-hexylthiophene) (P3HT) hybrid film. In the hybrid film, P3HT chains were very highly doped by simple spin-coating of a FeCl3/nitromethane solution. Hybrid films doped by spin-coating exhibited power factors of 267 +/- 38 mu W m(-1) K-2, which is an improvement over that of hybrid films doped by conventional immersion, 103 + 24 mu W m(-1) K-2. The excellent thermoelectric performance is originated from the dramatically increased electrical conductivity by the sufficient doping of P3HT in the hybrid films.
