The Mesoscopic Structure of β-HMX-Based PBXs by Dissipative Particle Dynamics Simulation

摘要

The χ parameters and the repulsive parameters of different polymers and β-HMX(octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), the mesoscopic structures of β-HMX-based PBXs at different temperatures have been studied. The results shown that the compatibility among β-HMX and the polymer structure units (vinylidenedifluoride (VDF) and chlorotrifluoroethylene (CTFE), respectively) are increasing with temperature increasing. The temperature and Molar ratio of the polymers played the important role in wrapped process.
