Description
Detonation nanodiamond is a commercially available synthetic diamond that is obtained from the carbon of explosives. It is known that the average particle size of detonation nanodiamond is about 4–6nm [1]. There is a size distribution particles in typical hydrosols, so it is possible to separate smaller particles.
In this report we suggest a simple smaller nanodiamond separating method. This method based on using a modified centrifugation and dialysis. The method does not require hazardous or rare chemicals and high-energy or specific laboratory equipment.
The method allows for the production of the detonation nanodiamond hydrosol with a very sharp distribution in size, where more than 85% of particles have a size ranging 1–4 nm.
Obtained particles can be used as a raw material for constructing neutron reflector [2] or for medicine investigations [3].
A.V. Shvidchenko expresses gratitude to the Russian Foundation for Basic Research for its support (grant № 17-03-01217 А). TEM and AFM measurements were performed using equipment owned by the Joint Research Center “Material science and characterization in advanced technology” (Ioffe Institute, St.-Petersburg, Russia) with financial support by Ministry of Education and Science of the Russian Federation (id RFMEFI62114X0007).
