Preparation and thermal decomposition behaviour of ammonium perchlorate/graphene aerogel nanocomposites

Ammonium perchlorate/graphene aerogels (AP/GA) nanocomposites were prepared by sol-gel method and characterized by scanning electron microscope(SEM), elemental analysis and X-ray diffraction(XRD). Their thermal decomposition behaviours were investigated by TG-DSC-IR. The results indicate that AP is presented in the AP/GA nanocomposites with an average particle size of 69.41nm and occupied 94.4% of total mass. GA shows an obvious catalytic effect on the thermal decomposition of AP/GA. Compared to pure AP, the low temperature decomposition peak of AP/GA nanocomposites disappears, the high temperature decomposition peak temperature decreases by 83.7°C, and the total heat release reaches 2110 J/g.
