摘　　要：水热条件下合成了一个二维含能配位聚合物[Ag(pzta)]n(pzta=5-吡嗪基四唑)。运用TG-DSC热分析仪研究了配合物的热分解行为;在非等温条件下,采用Kissinger和Ozawa-Doyle两种方法,对配合物进行了非等温动力学研究,得到它的表观活化能(E=215.073 k J mol-1),热爆炸临界温度(Tb=328.2℃)和自加速分解温度(TSADT=324.2℃)。使用DFT-B3LYP方法,求得配合物的爆炸热(△Hdet=5.1847 kcal·g-1),爆速(D=9.925km·s-1)和爆压(P=53.32 GPa)。结果表明:配合物属于安定性较好、爆轰性能优良的含能配合物,而且对AP具有较好催化燃烧效果。A 2D energetic coordination polymer[Ag(pzta)]n(pzta=5-(pyrazinyl)tetrazole)was prepared by hydrothermal synthesis.Thermal decomposition character of the complex was studied by means of TG and DSC thermal analyzer.Under non-isothermal condition,the apparent activation energy(E=153.63 kJ mol^-1)was obtained via the Kissinger's and Doyle Ozawa's two methods,the thermal explosion critical temperature(T b=328.2℃)and the self-accelerating decomposition temperature(T SADT=324.2℃)were researched by non-isothermal kinetics.The explosion heat(△H det=5.1847 kcal·g^-1),detonation velocity(D=9.925 km·s^-1)and detonation pressure(P=53.32 GPa)of the complex were obtained by the DFT-B3LYP method.In a word,the complex shows excellent detonation performance,good stability,and better catalytic combustion effect on AP.
