Thermal Degradation of Single-Walled Carbon Nanotubes
نویسندگان
چکیده
An optical absorbance technique was used to study the burning temperature and burning mechanism of vertically aligned single-walled carbon nanotube (VA-SWNT) films. Use of this simple optical method is shown to be consistent with the standard thermogravimetric analysis (TGA) method, but can be applied to a very small amount of SWNTs. Experimental results indicate burning of the VA-SWNTs is not localized, but occurs throughout the film. Furthermore, thicker films have a slightly higher burning temperature than thinner films synthesized under the same conditions. This is believed to be due to a higher bundle density and more uniform distribution of SWNTs within the film.

An Experimental Study on the Thermal Conductivity of Carbon Nanotubes/Oil (TECHNICAL NOTE)
[if gte mso 9]> In the present work, the thermal conductivity coefficients of nanoparticle-oil suspensions for two types of carbon nanotubes, single-walled (SWNTs) and multi-walled (MWNTs) carbon nanotubes at 0.1, 0.2 and 0.3 wt.% were measured by a modified transient hot wire method (KD2-pro thermal property meter). Results showed that the thermal conductivity of suspension containing single-...

The effects of Single Walled Carbon Nanotube (SWCNT) on mixed convection in a cavity are investigated numerically. The problem is studied for different Richardson numbers (0.1-10), volume fractions of nanotubes (0-1%), and aspect ratio of the cavity (0.5-2.5) when the Grashof number is equal to 103. The volume fraction of added nanotubes to Water as base fluid are lowers than 1% to make dilute ...
