Аннотация:Microcapsulation of titanium dioxide nanoparticles in polyethylene glycol PEG 8000 is performed under pulsed expansion of a jet of polymer solution in supercritical carbon dioxide into the background medium of sulfur hexafluoride and carbon dioxide. Either globule-shaped microcapsules or a film consisting of the product of the bulk intermolecular condensation of the coils are deposited on a substrate. The dependence of the quality and composition of the product deposited from the jet on the type of the background gas and its pressure in a range from 0.125 to 3 atm is investigated.
