Experiment and Molecular Dynamic Simulation on Performance of 3,4-Bis(3-nitrofurazan-4-yl)furoxan (DNTF) Crystals Coated with Energetic Binder GAP

To investigate the crystallization of DNTF in modified double-base propellants, glycidyl azide polymer (GAP) was used as coating material for situ DNTF, and performance investigated to inhibit crystallization. The results show that GAP can form a white gel on surface crystals has good effect which significantly reduce impact sensitivity friction DNTF. Molecular dynamics construct bilayer interface model with different growth crystal surfaces, calculations binding energy mechanical properties composite system were carried out. showed could effectively improve values K/G, γ ν are higher than those crystals, C12-C44 positive, indicating ductility while also improving toughness. Combining experimental simulation calculations, energetic binder be referred better cladding layer is feasible inhibiting problem propellants.
