Zusammenfassung:	FIELD: nanotechnologies. ^ SUBSTANCE: invention is related to biocides, and more precisely to method for preparation of hydrosols, which contain liquids as carriers of dispersed solid nanoparticles with coating in the form of capsules. Method includes saturation of dispersion liquid medium with clusters produced by erosion of material in electrodes, which are placed into liquid medium, under action of pulse electric discharges, with formation of shell on surface of clusters in process of their chemical interaction with elements of liquid medium. In dispersion liquid medium, having pH in the range of 5-9, between electrodes from metals, melts or semiconductors, arc pulse discharges are ignited with duration of 10-6-10-8 s, current pulse of which has shape of amplitude-modulated oscillating signal of ultrahigh frequency, besides specific energy in pulse makes at least 103 J/cm2, and shell is formed on surface of clusters with size of 0.3-50 nm from compounds on the basis of hydrogen and/or oxygen and/or carbon with thickness of 0.1-1.0 nm. ^ EFFECT: method provides for the possibility of technological control over process of clusters formation with specified size in dispersion medium during automatic application of various protective shells on them for production of leading edge hydrosol with unique consumer properties. ^ 3 cl, 3 dwg, 4 ex Изобретение относится к биоцидам, а более конкретно к способу приготовления гидрозолей, содержащих жидкости в качестве носителей диспергированных твердых наночастиц с покрытием в форме капсул. Способ включает насыщение дисперсионной жидкой среды кластерами, полученными эрозией материала электродов, помещенных в жидкую среду, под действием импульсных электрических разрядов, с формированием на поверхности кластеров оболочки при их химическом взаимодействии с элементами жидкой среды. В дисперсионной жидкой среде, имеющей рН в диапазоне 5-9, между электродами из металлов, сплавов или полупроводников зажигают дуговые импульсные разряды длительностью 10-6-10-8 с, импульс тока которых имеет форму модулированного по амплитуде колебательного сигнала сверхвысокой частоты, при этом удельная энергия в импульсе составляет не менее 103 Дж/см2, и формируют на поверхности кластеров размером 0,3-50 нм оболочку из соединений на основе водорода и/или кислорода, и/или углерода толщиной 0,1-1,0 нм. Способ обеспечивает возможность технологического управления процессом формирования в дисперсионной среде кластеров заданных размеров при автоматиче
