摘要
The pyrolysis behavior of hexanitrohexaazaisowurtzitane (HNIW) and HNIW/nano-Aluminum are investigated by non-isothermal differential scanning calorimetry/thermogravimetry/Pyrolysis-mass spectrometry/Fourier transform infrared spectroscopy (DSC/TG/Py-MS/FTIR) coupling analysis. The result shows that nano-Al improves the thermal stability of HNIW by swinging the very beginning of pyrolysis from synchronous bond cleavage of the highly strained molecular to the formation of HONO free radical corresponding with the increment of apparent activation energy. After the initial stage, nano-Al catalyzes the pyrolysis pathway to primary cleavage of C–N bond and releasing hyperbaric unstable N2O, which sequentially reacts with other gaseous products and Al.
