Abstract

Five kinds of graphene nanoplatelet-modified explosive lead styphnate composites (GLS) have been synthesized with different GNPs content from 0.1 to 2.0 mass% and characterized by SEM, XRD and Raman spectra. The initial thermal decomposition behaviours were studied by DPTA, and the complete thermal decompositions were studied by DSC and TG for the everlasting thermal stability of explosives in storage and application. The effects of GNP contents on thermal decomposition were investigated. The evolved gas amount from DPTA test indicates that GLS 1.0 % has the best thermal stability at ambient storage conditions. According to TG and DSC tests, the characteristic temperatures of thermal decomposition (T_p and T_b), the thermodynamic parameters (ΔS^≠, ΔH^≠ and ΔG^≠), the kinetic parameters (E_a and A) also confirmed this view. The results indicate that the GNP plays two opposite roles in their thermal decomposition processes, the catalysis reaction and hindering thermal conduction.
