Mass-spectrometric investigation of gases evolved by fluorinated single-wall carbon nanotubes during heating

Mass-spectrometric investigation of gases produced by heating in vacuum fluorinated single-wall nanotubes (with fluorine content of 25 mass %) which have been kept in air was carried out. It has been shown that nanotubes, which are preliminary, treated in vacuum at 23 °C, being heated in the temperature range from 23 to 100 °C produce generally H2O, CO and CO2. The gases containing fluorine appear in the range from 100 to 150 °C. In the range of 150–300 °C the mixture of disintegration products contain molecules COF2, and in the range of 300–400 °C mostly CF4 and C4F6 appear.
