Abstract:
In this research, a group of new energetic coordination nanomaterials (CNMs) based on functionalized graphene oxide sheets (FGS) have been designed and characterized. GO was first functionalized with N-rich energetic ligands such as triaminoguanidine (TAG), and then the resulting FGS was coordinated with metal ions to prepare energetic CNMs with high thermostability and insensitivity to mechanical stimuli. The density of GO–TAG–Cu(ii)/Cu(i) is as high as 3.14 g cm⁻³, while it has a Tₚ of 495 °C and VoD of 7723 m s⁻¹ by using 40 wt% ammonium perchlorate as the oxidant. These insensitive (Iₘ > 81 J) and highly thermostable energetic CNMs in combination with oxidizers are good candidate ingredients of low-vulnerability solid propellants and charges of deep-well perforating guns.
