The object of study - the process of obtaining resistant bimetallic sols - dispersions metals Ag + Cu - of hydrophilic and hydrophobic dispersion medium and polymer concentrates (master Butch materials). Purpose - a scientific basis and receive organ- and stabilized hydrosol with a combination of ultrafine (nano-size) particles of silver and copper, which makes it possible to produce polymer concentrates (master Butch materials) new types for a wide range of plastic products with bactericidal and fungicidal properties in traditional thermoplastic processing technology devices and control the particle size that is critical to the effectiveness of their biological effects. Research Methods - a set of physical, chemical, colloid-chemical methods, translucent and scanning electron microscopy, laser correlation spectroscopy, X-ray analysis and others. The report presents the results of research on the development processes of hydro and orhanozoley stabilized with a combination of ultrafine (nano-size) silver and copper. With the use of physical and colloid chemistry methods in the course of theoretical and experimental work has developed a number of processes of in water, water-organic and organic media sols ultrafine particles of silver and copper with the ability to control their size, giving them the aggregative stability at different concentrations of solids. A decision on the use of receiving runoff dispersions and nano particles mikrorozmirnyh these metals in different natural environments to produce concentrates (master Butch materials) for the manufacture of a wide range of products with bactericidal and fungicidal properties which can have a wide range of applications in food technology , medical and industrial use and so on.
