Preparation of Globular Nano-Aggregates Using Microemulsion Crystallisation

Popis výsledku v původním jazyce

Crystallisation - Aqueous microemulsions of hydrophobic organic liquids are used to be applied in some cases for separation of soft microparticles from aqueous dispersions in a regime of ?oil flotation?. A mechanism of this separation is based on different wetting of particles by water and organic liquids. A reverse way of this process can be applied on a molecular level when different wetting is replaced by different solubility of some molecules in both phases of a microemulsion. Elemental nanoparticles ? C60 macromolecules are well soluble in toluene (3.2 mg/l) in contrast to water. By a method of emulsion crystallization globular nanoparticles of required size, stability in aqueous dispersion can be prepared. The 50 % solution of C60 in toluene after mixing with water by intensive turbulence in an ultrasound bath was transferred into a microemulsion with a maximal portion of droplets with the radius of 381.6 nm. During continual bubbling under lower pressure this emulsion was perman
