Optimizing Carbon Nanotubes Shorter carbon nanotubes are easier to make, but, when assembled into fibers, the resulting fiber properties are much poorer than might be predicted by theory. Conversely, longer carbon nanotubes have much better properties but are harder to process. Behabtu et al. (p. 182) combined the best of both worlds through scalable wet spinning method, in which they dissolved longer carbon nanotubes and then spun them into fibers that showed excellent strength, stiffness, and…

Macroscopic weavable fibers of carbon nanotubes with giant thermoelectric power factor
TLDR
The observed giant power factor originates from the ultrahigh electrical conductivity achieved through excellent sample morphology, combined with an enhanced Seebeck coefficient through Fermi energy tuning, which makes these fibers strong candidates for the emerging field of thermoelectric active cooling, which requires a large thermoelections power factor and a large thermal conductivity at the same time.
