Аннотация:The major problem in producing of monodispersed diamond colloids lies in the necessity of deagglomeration of detonation soot and/or of removing of clusters formed by already isolated core particles in dry powders. Detonation nanodiamond (DND) is a suitable source material to produce a unique samples consisting of almost uniform diamond nanocrystals (d=3-5 nm). In the absence of dispersity control at various stages of preparation the reproducibility of properties of existing nanodiamond materials is poor. The DSC method could be of general use to monitor dispersity of powders of carbon nanomaterials (CVD diamonds, fullerenes, nanotubes, nanohorns). DSC traces are useful for predicting properties of corresponding dispersions.
