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.
