Abstract
A new energetic fullerene derivative [60]fullerene-poly(glycidyl nitrate) (C60-PGN) was synthesized through a modified Bingel reaction of C60 and bromomalonic acid PGN ester in the presence of amino acid and dimethyl sulfoxide. The obtained product was characterized by nuclear magnetic resonance, Fourier transform infrared spectroscopy, and ultraviolet–visible spectroscopy. Results confirmed that C60-PGN was synthesized successfully. The thermal decomposition analysis of C60-PGN was investigated by differential scanning calorimetry and thermogravimetric analysis with infrared spectroscopy, which revealed that C60-PGN exhibits good resistance to thermal decomposition up to 200 °C. The kinetic parameters of the thermal decomposition of C60-PGN were also obtained from the differential thermal analysis data by Kissinger and Ozawa–Doyle methods, with Ea = 170.85 and 168.29 kJ·mol–1, respectively. C60-PGN exhibits stability higher than that of any other known polynitrofullerenes.
