Thermoelectric (TE) measurements were compared for iodine-doped composites of carbon nanotubes (CNTs) with poly(3-hexylthiophene-2,5-diyl) (P3HT) having different degrees of regioregularity. Regioregular P3HT gave much higher power factors, showing t

Conjugated polymers are attractive novel materials whose properties may be tunable after their primary synthesis, by changing their redox state along with their charge while concomitantly dedoping/redoping with appropriate counterions. They can also
