Mass‐Spectrometric Investigation of Gases Evolved from Fluorinated Multi‐Walled Carbon Nanotubes at Heating

Abstract

The mass‐spectrometric investigation of the gases evolved from fluorinated multi‐walled carbon nanotubes under heating was carried out. It was shown that in temperature interval from 20°C to 120°C the gases are composed predominantly of CO₂, CO and H₂O. Molecules of COF₂ can be finding in gas phase of products of decomposition at 120–300°C. Molecules of CF₄ and C₂F₆ realized from fluorinated nanotubes at 300–450°C.
