description: The subject of the graduate qualification work is Â« Preparation and study of polymer nanocomposites with antibacterial properties Â». The given work is devoted to the study of methods for obtaining composites based on polylactide with the addition of Poviargolum. Their mechanical properties were studied, as well as antibacterial and antibiofilm activities.Composite films were obtained by the melt method and the casting method. The surface of the films and the degree of dispersion of the filler were studied by optical and scanning electron microscopy. Of the two methods presented, the melt method was chosen, since the films obtained by this method had a higher degree of dispersion of the filler.As a surgical suture material, composite monofilaments obtained in an extruder from polylactide and Poviargol, from a melted compound PLA + Poviargol, and from composite films were studied. The surface of the fibers obtained without pre-treatment in the extruder was smooth, that is, there were no filler particles on the surface of the monofilaments. In this regard, alternative methods for producing monofilaments were investigated, with the help of which the filler came to the surface of the fibers and created a biologically active surface. Monofilaments with concentrations of 1 and 5 mass % Poviargolum, obtained from the melt compound, were chosen as optimal for further research. It is shown that the deformation-strength characteristics of this thread satisfy GOST 31620-2012, and also have anti-biofilm activity.
