    Abstract:

    In order to study the performance of energetic metal-organic framework (E-MOFs) with dual ligands, MOF(Zn)-1, an E-MOFs containing dual ligands were prepared by hydrothermalmethodusing 3-amino-1,2,4-triazole, 3,5-diamino-1,2,4-triazole and zinc formate as raw materials. The growth mechanism of MOF(Zn)-2 with 3-amino-1,2,4-triazole as ligand and MOF(Zn)-3 with 3,5-diamino-1,2,4-triazole as ligand were studied. The crystal structures of MOF(Zn)-1, MOF(Zn)-2 and MOF(Zn)-3 were analyzed by X-ray single crystal diffractometer. Results show that MOF(Zn)-2 and MOF(Zn)-3 both belong to orthorhombic system while MOF(Zn)-1 belongs to triclinic system. The study of differential scanning calorimetry (DSC) combined with thermogravimetric analysis (TG) shows that there is only one intense exothermic process for all three materials. The decomposition temperatures of MOF(Zn)-1, MOF(Zn)-2 and MOF(Zn)-3 are 317.5, 301.5 ℃ and 308.2 ℃ at a heating rate of 5 ℃·min-1, respectively. The sensitivity test shows that the above three materials are insensitive energetic materials (IS > 40 J, FS > 360 N, and ESI > 24.75 J). Because of the relatively high density (MOF(Zn)-1: 2.069 g·cm-3; MOF(Zn)-2: 2.177 g·cm-3; MOF(Zn)-3: 2.222 g·cm-3), the predicted detonation performances are relatively good (MOF(Zn)-1: D = 5.9 km·s-1,p = 17.88 GPa; MOF(Zn)-2: D = 6.0 km·s-1, p =19.38 GPa; MOF(Zn)-3: D = 6.5 km·s-1, p = 22.17 GPa).
