Abstract
The present invention relates generally to methods of making carbon nanotubes, and more particularly to the interaction of single wall carbon nanotubes with hydrazoic acid to introduce energetic azide groups into the nanotubes to form activated carbon nanotubes.
Claims4
A method of making an activated single walled carbon nanotube (SWNT) having a tubular single wall and a plurality of metal azides inside the tubular single wall, comprising:
- providing the SWNTs, wherein the SWNTs further comprise at least one metal inside the tubular single wall;
- and
- reacting the SWNTs with hydrazoic acid for addition to the SWNTs to form metal azides inside the tubular single wall, wherein the hydrazoic acid is in a gaseous state.
