Al/CuO/GO composite nanoenergetic materials were prepared by self-assembly. In this text, SEM, TEM, XRD, FTIR, XPS, TA-IR, TG-DSC were used to characterize Al/CuO/GO. The results show that the addition of graphene oxide decreased the initial reaction temperature of Al/CuO, indicating that graphene oxide promoted the reaction of Al/CuO. The exothermic energy of Al/CuO/GO (1 wt %) is 2089 J/g, which is 705 J/g higher than that of the Al/CuO without graphene oxide prepared by solvent ultrasonic method. When the content of graphene oxide exceeds a certain value, the increase of graphene oxide content will cause the decrease of reaction heat release of Al/CuO/GO. The results of thermal analysis infrared combined test show that graphene oxide promoted the reaction of Al/CuO.
