Compared with isolated single-walled carbon nanotubes (SWNTs), thermal conductivity is greatly impeded in SWNT bundles; however, the measurement of bundle size effect difficult. In this study, number SWNTs a was determined based on transferred horizontally aligned suspended micro-thermometer to quantitatively study conductivity. Increasing significantly degraded For SWNTs, approximately 5000 ± 1000 W m–1 K–1 at room temperature, three times larger than that four-SWNT bundle. The logarithmical deterioration resulting from increased can be attributed scattering rate neighboring kinetic theory.
