Abstract
The stability of aqueous dispersions of detonation nanodiamonds (ND) in the presence of polyvinyl alcohol (PVA) has been studied. It has been established that PVA additives with a concentration above 0.1 wt.% cause the formation of aggregates. To increase the stability of ND dispersions, it was proposed to add a stabilizer, an anionic surfactant sodium dodecyl sulfate (SDS), into the system. As a result of the simultaneous action of the SDS-PVA mixture, the aggregation stability of aqueous dispersions of ND increases markedly; the particle size in the dispersions does not change for several days.
