The article considers an environmentally friendly method for producing copper nanoparticles in aqueous solutions via reduction by glucose
in the presence of polyvinyl alcohol; optimal synthesis conditions have been selected. The resulting copper nanoparticles are stable, spherical in shape, with diameter ranging from 20 to 130 nm, they do not precipitate and do not change color for 3-4 weeks. Electron microscope images confirm the formation of a thin polymer film on the surface of the cellulose fiber and show a change in the morphological surface of the treated samples compared to untreated ones. The physical, chemical and antibacterial properties of cellulosic materials modified with copper nanoparticles have been investigated. It has been shown that cellulosic materials modified with copper nanoparticles have antibacterial action.
Key words: cellulose textile materials, modification, copper nanoparticles, antibacterial properties.
