Abstract
The present disclosure relates to a composition that includes a film having a network of randomly aligned carbon nanotubes, where the carbon nanotubes have an average diameter between about 0.6 nm and about 2.0 nm and the carbon nanotubes form bundles having an average diameter between about 3 nm and about 50 nm. In addition, the composition is characterized by a power factor α2σ between 1 μW/mK2 and about 3500 μW/mK2 and by ZT=α2σT/k between about 0.02 and about 2.0 over a temperature range between about 100 K and about 500 K.
