Thermal conductivity of individual multiwalled carbon nanotubes
نویسندگان
چکیده
Thermal conductivity of individual multiwalled carbon nanotubes (MWCNT) is measured using a pulsed photothermal reflectance technique. Intrinsic thermal conductivity of individual MWCNT with a diameter 150 nm and length 2 mm at room temperature is extracted to be 2586 W/mK. Individual MWCNT is surrounded by SiO2, so parallel resistor model is applied in which SiO2 supportive is treated as a conducting channel that transports heat in parallel with MWCNT. 2012 Elsevier Masson SAS.

متن کاملThermal conductivity of multiwalled carbon nanotubes
Thermal conductivity of multiwalled carbon nanotubes ~CNT’s! prepared using a microwave plasma chemical vapor deposition system is investigated using a pulsed photothermal reflectance technique. We find that the average thermal conductivity of carbon nanotube films, with the film thickness from 10 to 50 mm, is around 15 W/m K at room temperature and independent of the tube length. Taking a smal...

We have measured the temperature-dependent thermal conductivity T of boron-carbon-nitride B-C-N and boron nitride BN nanotube mats. The thermal conductivity of B-C-N nanotubes is phonon dominated and reflects dimensional effect below 70 K. We employ a new analysis method to estimate the intrinsic T of BN nanotubes converted from B-C-N nanotubes, and find that at room temperature T of a multiwal...

The thermal conductivity and thermoelectric power of a single carbon nanotube were measured using a microfabricated suspended device. The observed thermal conductivity is more than 3000 W/K m at room temperature, which is 2 orders of magnitude higher than the estimation from previous experiments that used macroscopic mat samples. The temperature dependence of the thermal conductivity of nanotub...
