Nano-RDX Electrostatic Stabilization Mechanism Investigation Using Derjaguin-Landau and Verwey-Overbeek (DLVO) Theory

Abstract

This work investigates the electrostatic stabilization mechanism of 1,3,5-trinitroperhydro-1,3,5-triazine (Nano-RDX) suspensions at different electrolyte concentrations using Derjaguin-Landau and Verwey-Overbeek (DLVO) Theory. The van der Waals attractive forces were computed at different Nano-RDX crystal sizes and showed that those forces increased at smaller crystal sizes because of an increase in surface area. The electrical repulsion force was also computed with the thickness of the double layer (Debye length) and showed that the force decay increased with ion concentration. The thickness of the double layer is reduced significantly at greater ionic strengths. Finally, the total interaction energy was calculated as a function of electrolyte concentration and predicts that 100 nm Nano-RDX particles could be stable at low concentration of 0.001 mole/l and unstable at 0.1 mole/l. The DLVO theory could serve as a basic framework to study the electrostatic stability of Nano-RDX suspensions at different electrolyte concentrations.
