Preparation and laser response of graphene oxide complexes for typical polynitramine energetic materials

Abstract

The conflict between polynitramine energetic materials’ high energy density and its safety has been a challenge in its safe and efficient application. GO has been demonstrated to be promising materials for the regulation of energetic materials’ performance with various advanced preparation methods. However, the thermal-based performance of GO-based polynitramine energetic composites haven’t been deeply investigated. In this work, the GO@RDX and GO@CL-20 composites were obtained with the simple solvent evaporation method. GO-based polynitramine energetic composites’ structure was identified with SEM, PXRD, IR, and XPS, its thermal based performance was investigated with DSC, activation energy, and laser initiation system. This work could provide basis for the design of novel energetic composites with excellent comprehensive performance.
