A New Facile Strategy for Multifunctional Textiles Development through In Situ Deposition of SiO₂/TiO₂Nanosols Hybrid

Abstract

Herein, antibacterial activity and water repellent cotton fabrics with UV protection were carried out through in situ chemical deposition of SiO2 nanosols. Ammonium hydroxide was used as a gentle catalyst to initiate the polycondensation reaction inside the fabrics. During deposition of SiO2 nanosols onto cellulose of cotton, the process was integrated with TiO2 nanosols to evaluate the cooperative properties of the formed SiO2/TiO2 nanosols onto cotton fabrics. Furthermore, the water repellent property was induced to the loaded cotton fabrics by further polycondensation with octamethyltrisiloxane (OMTS). Results revealed that both SiO2 and TiO2 as well as mixtures therefrom were in situ deposited onto cotton fabrics, separately, in sizes ranging from 5–10 nm as indicated from TEM. Results from XRD and FTIR clearly proved, respectively, the crystallographic profile and chemical structure of nanosols loaded inside cotton fabrics. By comparing the obtained results, UV protection and water repellent combined with high antibacterial activity of cotton fabrics were successfully induced by a virtue of the in situ deposition of SiO2 nanosols into cotton fabrics. However, these properties were significantly improved with increasing the portion of TiO2 nanosols in mixture without breakdown in mechanical properties of cotton fabrics.

Green Synthesis of Zinc Oxide Nanoparticles (ZnO-NPs) Using Arthrospira platensis (Class: Cyanophyceae) and Evaluation of their Biomedical Activities

“…Nanoparticles (NPs) can be fabricated by different methods including chemical, physical, and biological methods. The former chemical and physical methods utilized hazardous material, needed harsh conditions such as temperature, energy, and pressure, and they can produce hazardous by-products [ 2 , 5 ]. Therefore, the interest increased in biological methods or green nanotechnology.…”

Bactericidal and In-Vitro Cytotoxic Efficacy of Silver Nanoparticles (Ag-NPs) Fabricated by Endophytic Actinomycetes and Their Use as Coating for the Textile Fabrics

“…Nanoparticles (NPs) are referred to as those particles with a size ranging between 1 and 100 nm and with distinctive physico-chemical properties [ 5 , 6 , 7 ]. There are many different approaches to the fabrication of NPs, including physical, chemical, and biological methods [ 8 , 9 , 10 ]. Recently, due to the spread of infections in hospitals amongst both patients and medical staff, it has become urgent to develop medical textiles based on nanotechnology in order to provide smart properties such as resistance to pathogenic microbes and UV protections [ 11 , 12 ].…”

Optimization of green biosynthesized visible light active CuO/ZnO nano-photocatalysts for the degradation of organic methylene blue dye

“…In recent years, nanomaterials in their different forms, shapes, and sizes have been discovered to be efficient in the removal of dye contaminants through photocatalytic activities [ 10 , 11 ]. This is attributed to their unique physicochemical properties such as their structures, high mechanical strength, high width-to-height ratio, high thermal and electrical conductivities, slight advantage metal/semi-metallic weight and behavior, and high surface area [ 12 , 13 , 14 , 15 , 16 ]. Various types of nanomaterials, such as copper, zinc, and titanium, are employed in various treatments of dyes, including precipitation, decolorization, adsorption, and photo-degradation, as well as in the treatment of textile waste dyes [ 17 , 18 , 19 ].…”
