Abstract: Nanodiamond dispersions in water and DMSO were stabilized with adsorbed layers of nonionic surfactant Igepal CA-630. Adsorption isotherms of Igepal CA-630 onto nanodiamonds from water and DMSO reveal the structure of the adsorbed layers. The stabilized aqueous dispersions retain their resistance to aggregation for at least 7 days, while the dispersions in DMSO are stable for 3 days.

Keywords: detonation nanodiamonds, adsorption, nonionic surfactant, Igepal CA-630, spectrophotometry, IR spectroscopy, dynamic light scattering, dispersion stabilization.
