Stability of Detonation Nanodiamond Colloid with Respect to Inorganic Electrolytes and Anionic Surfactants and Solvation of the Particles Surface in DMSO–H2O Organo-Hydrosols

In this article, the stability of sols detonated nanodiamonds, DND, with positively charged colloidal particles, is studied in different salt solutions water–dimethyl sulfoxide (DMSO) binary systems containing 95 vol.% organic solvent. Additionally, several CCC values are determined acetonitrile for comparison. The critical coagulation concentrations (CCC) using dynamic light scattering technique and Fuchs function. As coagulators, NaCl, NaBr, NaNO3, NaClO4, Nan-C8H17SO3, Nan-C12H25OSO3 used. Comparison DMSO–H2O CH3CN–H2O those obtained water allows us to make some conclusions. variations these solvents explained terms good poor interfacial solvation “structural” contribution interparticle interaction energy, lyotropic series anions, more or less pronounced adsorption surfactants. study DND hydrosol anionic surfactants hydrocarbon tail length demonstrated crucial role process.
