Description
Technical field: the invention belongs to the manufacture field of Nano diamond, its application relates to Ultraprecise polished, the compound plating of workpiece of artificial lens, the break-in oil of engine and the fields such as enhancing of material.
Background technology: the reason that the suspension of Nano diamond in water is difficult for stable existence mainly is because the surface of Nano diamond can be very high, in order to reduce the energy of system, often reach stable state between particle by drawing close mutually, also have, particle is thinner, distance between the particle is shorter, Van der Waals force between the particle impels them to reunite, in addition, effects such as the hydrogen bond on Nano diamond surface, the wet bridge of absorption also can cause the coalescent of particle, coalescent direct result is that the second particle particle diameter becomes big and sedimentation takes place, and causes the instability of system.
The reunion technology of separating of nano particle can be described as the prerequisite that nano-powder is effectively used.After the detonation synthesizing nano diamond is achieved success, carry out the research worker of application and development, with he (she) research emphasis be placed on it and separate aspect reunion technology and the stably dispersing in different systems thereof.Chigandva (G.A.Chigandva, V.A.Boonger, A.S.Chiganov.Colloid J.1993,55 (5): 774～775) use saturated AlCl
