- Аннотация: Surface modification of cotton fabric with silver (Ag) nanoparticles (NPs) to impart hydrophobic and antibacterial properties faces two major challenges: poor adhesion of the NPs to the surface and fabric discoloration. To overcome these drawbacks, we proposed a simple strategy for surface modification of cotton fabric using hexagonal boron nitride (BN) NPs decorated with diethylenetriamine (DETA)-modified Ag NPs (fabric-Ag/BN-DETA). Ag NPs of 1–10 nm in size were synthesized on the surface of hollow 10–100 nm h-BN NPs via UV-induced decomposition of silver nitrate. The successful attachment of Ag/BN-DETA NPs to the fabric surface was confirmed by XRD, XPS, IR spectroscopy and surface wettability measurements. Decorating the cotton surface with Ag/BN and Ag/BN-DETA NPs did not alter the fabric color. DETA in fabric-Ag/BN-DETA acts as a fixative, ensuring strong retention of Ag/BN on the textile surface and promoting the generation of reactive oxygen species (ROS), the amount of which gradually decreased from 12 (0.25 h) to 8.6 (6 h) and 3.3 (24 h) μmol/L. The Ag/BN-DETA-modified fabric was hydrophobic, machine-washable, demonstrated sustained Ag+ ion release over 5 days of exposure to water, and exhibited excellent bactericidal properties against Gram-negative Escherichia coli K261 and U20 strains and Gram-positive Staphylococcus aureus MW2 strains. Complete bacterial inactivation by the fabric-Ag/BN-DETA can be explained by the synergistic effect of Ag+ ions and ROS. The resulting fabric has promising potential for use in cotton medical products, including masks, gowns, patient clothing, hospital bed linen, etc.
