In situ synthesis of copper stearate/ammonium perchlorate shell–core composite for self-catalytic thermal decomposition

Abstract

In this study, copper stearate (CS) was investigated as a potential catalyst for the thermal decomposition of ammonium perchlorate (AP). Copper stearate/ammonium perchlorate (CS/AP) shell–core composite was prepared by in situ synthesis and characterized to sample by SEM and EDS, it shows that CS is evenly dispersed on the surface of AP and forms a shell–core structure. Through using DSC and analyzing the thermal decomposition performance of CS/AP composite,the results show that the thermal decomposition temperature of AP decreased with the increase of catalyst content,when catalyst content is 4%, the thermal decomposition temperature of AP goes down 78.4 °C, and its catalytic effect is best. CS/AP shell–core composite provides a fresh idea for the thermal decomposition of AP.
