| Abstract
| - The thermal decomposition of fluorinated single-walled carbon nanotubes (F−SWNTs), known to result inpristine SWNTs, has been investigated by freezing the gaseous products formed at temperatures between 50and 500 °C under high vacuum in an argon matrix at 10−20 K and analyzing the trapped species by IRspectroscopy. The major products of F−SWNT decomposition are carbonyl fluoride (COF2) below 300 °Cand CF4 above 300 °C. For comparison, graphite fluoride is stable thermally up to 300 °C under theseconditions, and the major gas-phase species at temperatures below 500 °C are CF4 and the CF3 radical.F−SWNTs are thermally less stable than graphite fluoride, and etching of the nanotubes is observed at lowerthermolysis temperatures.
