DISPERSION OF NANODIAMOND IN AQUEOUS SYSTEM

The effect of Chemical Mechanical Modification (CMM) and dispersants on the ζ potential of nanodiamond particles in aqueous system and the influence of the ultrasonic or shearing techniques on its size distribution were studied CMM and the addition of dispersants AD 2 and AD 8 improve the stability of its suspension With ultrasonic time prolonged, the mean average size of nanodiamond decreases, while with the prolongation of shearing time, its mean size decreases first, then increases a little In the speed range used, the mean size decreases with the rising speed If the whole ultrasonic time kept constant, it is better to add the dispersants before
