Abstract Silver‐containing composites formed by sputtering deposition on the surface of polylactide (PLA) films have been developed; they contain a layer silver nanoparticles different thicknesses depending time, namely 1, 3 and 5 min. It was found that with time min thickness ca 100 nm is formed. The average size Ag 5.9 nm, specific area S sp 97 m 2 g −1 . samples obtained were characterized wide‐angle X‐ray scattering, TEM, TGA DSC their antimicrobial, antiviral cytotoxic properties studied as well. thinnest (deposited for 1 min) has greatest effect PLA's heat resistance glass transition temperature. PLA‐Ag show antimicrobial activity against test cultures Staphylococcus aureus , Escherichia coli Pseudomonas aeruginosa increases increasing duration deposition. had weak virucidal herpes simplex virus type influenza A.
