METHOD OF PRODUCING COMPOSITE MATERIAL WITH ANTIMICROBIAL PROPERTIES BASED ON GRAPHENE OXIDE AND COPPER OXIDE NANOPARTICLES Russian patent published in 2019 - IPC A61K9/14 B82B3/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a method of producing a composite material with antimicrobial properties based on graphene oxide and copper oxide nanoparticles and can find application mainly in the field of nanobiotechnologies and nanomedicine for making preparations suppressing vital activity of pathogenic microorganisms. Invention relates to a method of producing a composite material with antimicrobial properties based on graphene oxide and copper oxide nanoparticles by mixing copper oxide with graphene oxide nanoparticles, according to the invention, copper oxide powder is initially ground in grinding drums of planetary mill filled with grinding balls at temperature of 40–80 °C for 1 to 3 hours, thereafter, obtained nanodispersed copper oxide is added in amount of 20–40 wt% of weight of copper oxide graphene oxide and synthesis of composite material is carried out in grinding drums at temperature of 60–80 °C for 4–6 hours. Synthesis of composite material is carried out at low rotation frequency by 20–30 %. For use, obtained composite material is diluted with water with concentration of composite material in solution from 0.02 to 0.5 wt%.

EFFECT: simple design, nanocomposite stability, antimicrobial activity.
