Novel Geminal Dinitro Esters As Energetic Plasticizers for GAP Binder

“…On the other hand, thermal kinetics analysis is also very crucial for long-term stability assessment on handling, storage, and processing stages. 19 Thus, DSC curves of DNEPs' thermal decomposition processes at different heating rates are measured accordingly. Thermal kinetic analysis details and calculation results of kinetic parameters were provided in the Supporting Information (Figures S4−S6, Tables S1−S3).…”

“…Calibration had been carried out before measurement with corresponding viscosity standards, and the given viscosity value is accurate to within 1% of its state value. 19 The viscosity of GAP and DNEPs mixtures are measured upon different temperatures and compositions, and part of the results are depicted in Figure 3, and all viscosity results were provided in Table S5 in the Supporting Information. All of the fluidity activation energies calculated by the equation of η ∝ exp(E vis /RT) are presented in Table 3.…”

“…It is found that the thermal decomposition temperatures as well as the onset temperatures are increased along with the increased alkane length in the main chain of DNEPs and is all higher than that of BuNENA (212.6 °C) and TADONA (236.8 °C) as well. On the other hand, thermal kinetics analysis is also very crucial for long-term stability assessment on handling, storage, and processing stages . Thus, DSC curves of DNEPs’ thermal decomposition processes at different heating rates are measured accordingly.…”

“…Therefore, to design and synthesize novel energetic plasticizers with very low T g and moderate energy properties becomes the keen concerns in the field of energetic materials. Recently, our group reported 1,2,8,9-tetraazido-4,6dioxol-nonane (TADONA) 19 as a promising multiazido ether energetic plasticizer for glycidyl azide polymer. Even though its high nitrogen content benefited in the environmentally benign decomposition products, there are still more improvementscould be made on the modulation of density, glass transition temperature to upgrade energetic and low temperature properties of propellant formulations.…”

Synthesis and Characterization of Azido Esters as Green Energetic Plasticizers

“…Four new compounds have been described, namely ethylene glycol bis(azidoacetate) (EGBAA), diethyleneglycol bis(azidoacetate) (DEGBAA), trimethylol nitromethane tris(azidoacetate) (TMNTA) and pentaerythritol tetrakis(azidoacetate) (PETKAA) [8]. Moreover, a series of new multi azido esters have been reported as promising plasticizers [9][10][11][12][13][14][15].…”
