- Abstract
In response to the demands for elevated energy levels and enhanced homogeneity in propellant and explosive formulations, new energetic composites based on unmodified and modified nanostructured cellulose nitrate and 3-nitro-2,4-dihydro-3H-l,2,4-triazol-3-one (NTO) were fully scrutinized. Indeed, microcrystalline cellulose nitrate (MCCN)/NTO, and carbamated microcrystalline cellulose nitrate (M3CN)/NTO composites were elaborated using a solvent evaporation method and their characteristics were compared to those of nitrocellulose (NC)/NTO. Experimental findings highlighted that the newly developed energetic composites exhibit favorable features, including a density exceeding 1.775 g/cm3. Moreover, theoretical performance calculations using EXPLO5 version 6.02.06 indicated that the optimal composition resulted in excellent specific impulses and detonation velocities, which increased from 217.5 s and 7910 m/s for NC/NTO to 235.1 s and 8165 m/s for M3CN/NTO. Structural analyses revealed a homogeneous dispersion and embedding of NTO particles within the nitrated cellulosic matrix. In addition, thermo-kinetic results demonstrated that the activation energy of the three designed energetic composites is lower than that of pristine NTO explosive. Therefore, this investigation offers a potential fabrication approach and basic theory for the application of nanostructured cellulose nitrate in advanced high-performance energetic formulations.
