采用原位傅里叶红外光谱法(FTIR)研究了Al H3/聚叠氮缩水甘油醚(GAP)混合体系的热解特性。结果表明:Al H3在100℃开始分解,180℃达最大分解速率,250℃左右分解完全;GAP在200℃左右叠氮基开始裂解,并形成亚胺中间体,主链的完全解聚相对滞后;Al H3改变了GAP的分解历程,Al H3/GAP在170℃开始分解,而且在分解过程中没有出现CN、CO等不饱和键,推测是由于Al H3具有较强的还原性。
In situ Fourier transform infrared spectroscopy (FTIR) was used to investigate the pyrolysis characteristics of Al H3 / polyazide azide (GAP) mixed system. The results show that Al H3 starts to decompose at 100 ℃ and reaches the maximum decomposition rate at 180 ℃ and completely decomposes at about 250 ℃. At about 200 ℃, GAP begins to cleave and form imine intermediate, ; Al H3 changed the decomposition process of GAP, Al H3 / GAP began to decompose at 170 ℃, and in the decomposition process did not appear CN, CO and other unsaturated bonds, presumably due to Al H3 has strong reducibility .
