Analysis of novel Energetic Coordination Polymers (ECPs), based on​ ​Graphene  Oxide (GO)-copper complex was performed by combining data from various analytical methods, including FTIR and Raman spectroscopies, XPS, EDS and combustion Elemental Analysis. The morphology of our ECPs was also studied by SEM and TEM and their sensitivity and detonation performances were determined. It was shown that these energetic nanomaterials are insensitive and highly thermostable. We believe that these properties are result of unique heat and impact dissipation capabilities of GO sheets. One of our novel materials exhibits high density (2.85 g·cm^–3), remarkably high thermostability (T_p = 456°C), and low sensitivity (I_m > 98 J; ESD of 1000 mJ). This material has a calculated detonation velocity of 7082 m·s^–, making it highly attractive for various civil and defense applications.
