METHOD FOR MANUFACTURE OF NANOCOMPOSITE MATERIAL WITH BIOLOGICAL ACTIVITY Russian patent published in 2017 - IPC C09D5/14 B82B1/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to a method of manufacturing a polymeric material with biological activity that is characterized by nanostructuring the surface with etching of gas ions followed by application of a film nano-sized coating comprising fluorine and carbon by ion-assisted precipitation in a vacuum. The method for manufacturing a material with biological activity comprises a substrate of a biocompatible polymer, preferably polytetrafluoroethylene or polyethylene terephthalate, comprising etching the surface of the substrate by ion-plasma treatment in a vacuum using tetrafluoromethane ions and then ionically stimulated deposition of the carbon-containing film from cyclohexane in a vacuum onto the nanostructured substrate surface. Nanostructuring of the substrate surface is carried out for 10-40 minutes, and a carbon-containing film-modifying film 0.3-1.0 mcm in thickness is formed from the plasma-forming mixture of cyclohexane and tetrafluoromethane vapour in the range of their content (vol. %): 62-32/35-65, respectively.

EFFECT: method ensured the formation of a two-layered matrix system, the increased antimicrobial properties of which are achieved automatically.
