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 69.41 nm 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℃,and the total heat release reaches 2 110 J/g.
