摘要：

As the result of successful disintegration of tight aggregates in detonation nanodiamond by stirred-media milling with microbeads, stable colloid of nanodiamond particles with a mean core size of 4 nm is obtained for the first time, but the colloid is colored deep black. X-ray diffraction, Raman scattering, HRTEM, UV-vis absorption spectra and viscosity data were used to characterize the colloid. It was suggested that the reason for the unexpected black color of the suspension is a result of graphitic partial surface (pi-electrons formation of 4 nm diamond particles) induced by strong collision with beads during milling process. pi-electrons are a reason of double electric layer formation and high viscosity of the suspension. Theoretical estimations fitted experimental data. (c) 2005 Elsevier B.V. All rights reserved.
