“…pH, temperature, reaction time, reactant concentrations and so on. The same implies also for silver nanoparticles (AgNPs) which can be prepared by reduction of AgNO3 by hydrazine hydrate [4], sodium borohydrate [5,6] both strong but rather hazardous reducing agents, by plants-derived compounds [7] or other "bio-inspired" reducing agents including saccharides [8] or living bacteria cells [9]. Also photochemical or electrochemical approaches have been reported [10,11].…”

In this work the possibility was investigated to synthesize in-situ silver nanoparticles (AgNP) on graphene oxide (GO) surface without commonly used additional reducing or alkalizing agents or increased temperature. Using diverse microscopic (AFM, TEM) and spectroscopic methods, it was proved that very small AgNPs were formed on GO by simple incubation for 2 hours a mixture of GO dispersion and AgNO3. The prepared nanomaterial (GO_Ag) was also assessed using electrochemical methods and it exhibited electrochemical behavior similar to GO_Ag nanomaterial prepared with a help of citric acid as a reducing agent. Furthermore, it was found that i) electrochemical reduction of the GO_Ag on electrode surface decreased the voltammetric response even though this step has increased the surface conductivity and ii) GO_Ag can be employed for sensing of chlorides with detection limit of 79 M and a linear range up to 10 mM. It could also provide electrochemical response toward chloroacetanilide herbicide metazachlor. Hence, the reducing capabilities of GO were proved to be applicable for insitu synthesis of metal nanoparticles with the highest possible simplification and the as-prepared nanomaterials could be employed for fabrication of different electrochemical sensors.

“…cerust can be ascribed to the synergistic effect of Ag-nanoparticles and the GO-nanosheets. The GO-nanosheets on the cotton fabrics occupied high specific surface area and hydrophobic character, resulting in increased barrier properties to diminish the adhesion and propagation of microorganisms from attaining the surface of fabrics [51]. Furthermore, the existence of GOnanosheets onto cotton fibers is greatly useful to the nucleation and creation of Ag-nanoparticles since they can work as the active surface to raise their distribution as well as their stability.…”

Multifunctional cotton textile nanocomposites are well developed by the functionalization of cotton with pure TiO2, Ag-, Fe-doped TiO2, and graphene oxide nanoparticles via sol-gel and modified Hummer methods. The treated fabrics materials are investigated by XRD, FT-IR, and SEM. The obtained treated fabrics have been used as an adsorbent for the methylene blue dye removal from aqueous solution. The functionalized cotton fabrics are tested for antimicrobial capability towards Escherichia coli, Bacillus cereus, and Candida albicans. All functionalized fabrics have higher antimicrobial activity compared to untreated cotton especially the fabrics containing silver and Fe doped TiO2. The optimum conditions of the adsorption process are determined via the study of the effect of the initial concentration of dye, pH, and contact time on the removal efficiency. Langmuir, Freundlich, and Tempkin isotherms are applied for the equilibrium adsorption data. GO-Cot and Ag-Ti@GO-Cot samples showed the highest adsorption removal activity. The linear correlation coefficient (R2) showed that the Temkin model well fitted the data of adsorption on the GO-Cot sample. The analysis of experimental data with different kinetic models showed that the pseudo-second-order kinetic model well fitted the adsorption data better than the other kinetic models of pseudo-first-order, Elovich, and the intra-particle diffusion.

At present, nanotechnology is a priority in research in several nations due to its massive capability and financial impact. However, due to the uncertainties and abnormalities in shape, size, and chemical compositions, the existence of certain nanomaterials may lead to dangerous effects on the human health and environment. The present review includes the different advanced applications of nanomaterials in textiles industries, as well as their associated environmental and health risks. The four main textile industry fields using nanomaterials, nanofinishing, nanocoatings, nanofibers, and nanocomposites, are analyzed. Different functional textiles with nanomaterials are also briefly reviewed. Most textile materials are in direct and prolonged contact with our skin. Hence, the influence of carcinogenic and toxic substances that are available in textiles must be comprehensively examined. Proper recognition of the conceivable benefits and accidental hazards of nanomaterials to our surroundings is significant for pursuing its development in the forthcoming years. The conclusions of the current paper are anticipated to increase awareness on the possible influence of nanomaterial-containing textile wastes and the significance of better regulations in regards to the ultimate disposal of these wastes.
