Abstract
The transition metal complexes of triaminoguanidine(TAG-M,where M=Cobalt(Co)or Iron(Fe))have been prepared.The catalytic effect of these complexes on the thermolysis of energetic composite based on nitrocellulose and diethyl-ene glycol dinitrate,has been investigated.Extensive characterization of the resulting energetic composites was carried out u-sing scanning electron microscopy(SEM),X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),and dif-ferential scanning calorimetry(DSC).Isoconversional kinetic analysis was performed to determine the Arrhenius parameters as-sociated with the thermolysis of the elaborated energetic formulations.It is found that TAG-M complexes have strong catalytic effect on the thermo-kinetic decomposition of NC/DEGDN by decreasing the apparent activation energy and significantly in-creased the total heat release.The models that govern the decomposition processes are also studied,and it is revealed that dif-ferent reaction processes are accomplished by introduction metal complexes of triaminoguanidine.Overall,this study serves as a valuable reference for future research focused on the investigation of catalytic combustion features of solid propellants.
