FIELD: technological processes.

SUBSTANCE: invention relates to processing of high-molecular polymer materials with organic compounds for coating application on the basis of carbon compounds. Described is a method of producing antimicrobial nanocomposite polymer materials formation of nanostructured surface of the polymer substrate by pretreatment of its surface with ions of chemically active and/or inert gases by changing the composition of gases for ion treatment of surface or modes of this operation, to produce relief with given mean square roughness (Rq), and subsequent application of nano-sized films based on carbon ion-induced deposition from gas phase of vapours of carbon-containing compounds, including sp²- and sp³-urothelial cells marked with carbon State , characterised by that the polymer substrate surface treatment with ions of active and/or inert gases is performed for 3-10 minutes at average energy of ions of 300-2,000 eV and current density 0.5-2 mA/cm², and nanosized carbon-containing film is made in the form of a multilayer structure, periodically varying voltage average energy of ions or alternation of gases forming pairs of carbon-containing compounds with constant energy of ions, thus controlling content of molecules nanolayers film number sp³- and sp²-hybridized carbon States the ratio of nanolayers of sp³-/sp²-hybridized carbon state is maintained within the range of 0.7-1.8.

EFFECT: providing the antimicrobial nanocomposite polymer material with high optical transmission and water-repellent properties.
