One of the methods to improve the sensitivity properties of explosives is their encapsulation and coating. Cyclotrimethylenetrinitramine (RDX), due to its good explosive power and reasonable cost, is one of the most widely used explosives in the world. However, its relatively high sensitivity to external stimuli such as impact, friction, and thermal shock poses significant limitations during production, transportation, storage, and utilization. Therefore, encapsulating and coating RDX explosives is crucial for enhancing safety in their application. The use of metal-organic frameworks (MOFs) is one of the methods for encapsulating various materials, including high-energy materials. In this research, a high-energy metal-organic framework (HE-MOF) based on the H₂BTO ligand and copper as the central metal ([Cu(BTO)(H₂O)₂]_n) was used as a coating material for encapsulating RDX. The results showed that the sensitivity properties of RDX, including impact and friction sensitivity, were improved by 257% and 200%, respectively, after encapsulation with [Cu(BTO)(H₂O)₂]_n.
