Synthesis, characterization and thermal decomposition performance of polyaminofullerene nitrate

A novel fullerene nitrate derivative, polyaminofullerene nitrate, with high nitrogen content was synthesized using bromofullerene Th-C60Br24 as a starting material. The composition of the obtained product was determined as C60(NH2)24·13HNO3 by ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. The thermal decomposition of C60(NH2)24·13HNO3 was observed by differential thermal analysis and thermogravimetric analysis with infrared spectroscopy. The results show C60(NH2)24·13HNO3 proceeded with a one-step exothermic reaction at 425 K. Kinetics parameters of the thermal decomposition C60(NH2)24·13HNO3 were obtained from the differential scanning calorimeter data, and the reaction mechanism was found in Mampel power model. Our work prepared a novel fullerene derivative by a facile method, and it has potential application in explosives and propellants additives.
