Development of photo-induced Ag0/TiO2 nanocomposite coating for photocatalysis, self-cleaning and antimicrobial polyester fabric

Materials with multifunctional surface, such as UV shielding, self-cleaning or antimicrobial properties have been highly desirable. Titanium dioxide (TiO2) and nanocomposite nano-particles (NPs) composed of metallic silver/titanium dioxide (Ag-0/TiO2) were prepared. Both of TiO2 nanoparticles and Ag-0/TiO2 nanocomposite were coated onto the surface polyester fabric utilizing the straightforward pad-dry-curing technique. The morphological properties and elemental composition were determined utilizing X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX). The resultant materials demonstrated photocatalytic and antimi-crobial properties. The photocatalytic performance was studied using the photochemical destruction of methylene blue, while the antimicrobial activity was recorded against Escherichia coli. The performance of polyester fabrics comprising Ag-0/TiO2 nanocomposite particles was much better than those containing pure anatase TiO2 nanoparticles. (c) 2021 The Authors.
