Preparation of Bicomponent Metal Nanoparticles for Giving Textile Materials Bactericidal Properties

Modification of cloths of natural silk, wool, and polyamide with copper-silver bimetallic nanoparticles to give them bactericidal and fungicidal properties was studied. The modified substrates were qualitatively evaluated using a JEOL JSM-6390 LA scanning electron microscope, Shimadzu FTIR-8400S FTIR spectrometer, DXR Raman Microscope RS spectrophotometer, and Hitachi S-4700 field emission scanning electron microscope. The substrates became colored during the modification. The color was characterized by reflectance spectra taken on a Shimadzu UV-2401PC spectrophotometer. Results of antibacterial and antifungal tests were given.
