Boron is traditionally used as an additive in energetic systems as a result of the high density of energy. In particular, the existence of the naturally formed boron oxide (B2O3) layer retards the reactivity by acting as a barrier if it cannot be efficiently removed. In this study, the new dicationic ionic liquid based on dicyanamide anoins was synthesized and used as a protective ligand for boron nanoparticles. The effects of newly synthesized ionic liquid are investigated by a combination of X-ray diffraction (XRD), energy-dispersive X-ray (EDX), scanning electron microscopy (SEM), dynamic light scanning (DLS), zeta-potential measurements, X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). It was found that this ionic liquid binds to boron well enough and protects the boron surfaces from oxidation during air exposure.
