摘要

The paper describes the study of the photocatalytic oxidation and antibacterial properties of cotton fabric treated with zinc oxide-silver (ZnO-Ag) nanocomposites. The ZnO nanoparticles were synthesized by an in situ approach on the surface of activated cotton fibers seeded with Ag nanoparticles. The effect of Ag nanoparticle-seeding and synthesis temperature on the morphological, thermal, photocatalytic and antibacterial properties of the ZnO-Ag nanocomposite-treated cotton fibers were characterized using scanning electron microscopy, energy dispersive X-ray spectroscopy. X-ray diffractometry, thermo gravimetric analysis, and Attenuated Total Reflection-Fourier Transform Infrared spectroscopy. Synthesizing ZnO nanoparticles on the surface of un-activated cotton fibers led to the formation of agglomerated nanoparticles while the Ag nanoparticle-seeded cotton fibers prevented this. The results indicated the presence of ZnO-Ag nanocomposites, on the coated cotton fabrics, and all loaded samples presented an inhibition zone against S. aureus and E. coil bacteria.
