“…These properties allow them to be widely used in sensor, optical, magnetic, and thermal devices, as well as in catalysis. Among metal nanoparticles, copper (Cu) nanoparticles are among the most widely used materials due to their lower cost, easy mixing with polymers [ 1 ], excellent electrical [ 2 ] and thermal conductivity [ 1 , 3 ], shorter reaction time compared with conventional catalysts [ 4 ], excellent solderability [ 5 ], low cytotoxicity [ 6 ], and antifungal and anticancer properties [ 7 ]. In the last decade, there has been a rapid increase in interest in textiles modified with copper particles, which acquire a number of useful properties, such as electromagnetic interference (EMI) shielding [ 8 ], high electrical conductivity [ 9 ], photocatalytic [ 10 ], hydrophobic [ 11 ], and especially antibacterial and antiviral properties [ 12 , 13 , 14 ].…”

Textile materials modified with copper-containing particles have antibacterial and antiviral properties that have prospects for use in healthcare. In the study, textile materials were saturated with copper-containing particles in their entire material volume by the absorption/diffusion method. The antibacterial properties of modified textile materials were confirmed by their inhibitory effect on Staphylococcus aureus, a Gram-positive bacterium that spreads predominantly through the respiratory tract. For the modification, ordinary textile materials of various origins and fiber structures were used. Technological conditions and compositions of modifying solutions were established, as well as the most suitable textile materials for modification. To assess the morphological and physical characteristics of copper-containing particles and the textile materials themselves, X-ray diffraction, a scanning electron microscope, and an energy-dispersive X-ray spectrum were used. In modified textile samples, XRD data showed the presence of crystalline phases of copper (Cu) and copper (I) oxide (Cu2O). On the grounds of the SEM/EDS analysis, the saturation of textile materials with copper-containing particles depends on the structure of the textile materials and the origins of the fibers included in their composition, as well as the modification conditions and the copper precursor.
