Synthesis and Characterization of [60]Fullerene-Poly(glycidyl nitrate) and Its Thermal Decomposition

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 E a = 170.85 and 168.29 kJ·mol–1, respectively. C60-PGN exhibits stability higher than that of any other known polynitrofullerenes.

Preparation and characterization of insensitive HMX/rGO/G composites via in situ reduction of graphene oxide

“…34,35 Therefore, the thermal stabilities of the prepared samples were investigated via differential thermal analysis (DTA). The DTA analyses were performed under an air ow of 50 mL min À1 with approximately 2 mg of sample and aAl 2 O 3 as the reference material.…”

Highly energetic compositions based on functionalized carbon nanomaterials

“…In general, C 60 can either be combined with energetic moieties, as shown above, or be functionalized with energetic polymers. Two novel fullerene-based energetic polymers have been prepared recently, including C 60 -poly(glycidyl nitrate) (C 60 -PGN, Cp-16) 120 and C 60 -glycidyl azide polymer (C 60 -GAP, Cp-17).…”

Synthesis and Characterization of a New Energetic Salt based on Dinitramide

“…Figure 7 depicts the IR spectra of the thermal decomposition gas at different decomposing temperature. The results showed that the decomposition products were mainly H 2 O (3540 cm –1 ), CO 2 (2360 cm –1 ), N 2 O (2247, 1274 cm –1 ), CO (2148 cm –1 ), and NO 2 (1630, 1590 cm –1 ),17,18 initially, because of the central nitrogen atom of dinitramide anion that bears two strongly electron‐withdrawing groups (nitro group). As the temperature rises, the dinitramide anion decomposed NO 2 firstly.…”
