Thermal Decomposition And Electron Microscopy Studies of Single-Walled Carbon Nanotubes

Thermoanalytical and electron microscopic studies were used as characterisation tools for the determination of the composition of single walled carbon nanotube samples. A purification method proved to be effective, resulting in a three fold increase in the percentage of SWNTs present in the purified product as determined by thermogravimetric analysis. In this work we report the thermogravimetric analysis by conventional and high resolution methods of the raw SWNTs and purified SWNTs
