- Abstract
Thermal desorption mass spectrometry has been used to study the desorption of fullerene C[sub 60] molecules from a mixture with a copolymer of trifluorochloroethylene and vinylidene fluoride. The temperature range of the C[sub 60] yield from the copolymer mixture is substantially lower (approximately 100 °C lower) than the temperature range for the sublimation of pure C[sub 60] molecules. The temperature range of the C[sub 60] yield from the copolymer mixture is the same as that for the desorption of HCl and HF formed as a result of copolymer cross linking reactions. The desorption of C[sub 60] from the copolymer mixture is a two-stage process correlated with the stages of HCL and HF formation for which the temperatures at the maximum desorption rates differ. The results suggest that the copolymer cross-linking processes and the desorption of C[sub 60] molecules are interrelated.
