Abstract
In this communication, a new method for the deaggregation of detonation nanodiamond (ND) and some preliminary results using this method are presented. ND is firstly graphitized in nitrogen at 1000°C and then oxidized by air at 450°C to remove the surface graphite layer formed. The sample after such treatment was suspended in water by ultrasonics, and the particle-size distributions were measured. It has been found that the diameters of more than 50% of the ND particles can be reduced to less than 50 nm.Keywords
