Abstract

This article investigates the process of obtaining polylactide film composite materials with the simultaneous formation of silver nanoparticles. Impact of polylactide and its composition (amorphous and amorphous-crystalline), and glycerol plasticiser on the kinetics of solvent evaporation is determined. To impart fungi bactericidal properties to polylactide composites, a silver reduction reaction by the interaction of argentium salts with polyvinylpyrrolidone was utilized. The formation of silver nanoparticles was confirmed by an energy-dispersive analysis of the composite. A fundamental technological scheme for the preparation/production of polylactide-based films with silver nanoparticles is proposed/suggested, which proves their effective practical use as packaging materials for/during food and drugs.
